Is there a way to make Abaqus/CAE generate text output file with the values of stress, temperature, etc. In the Node File tab, define *Node file for the selected Output block. The output request can be repeated as often as necessary to define output for different node sets. Each row of the table lists a slave node and the master nodes to which the slave node transfers load when in contact with the master surface. The *EL FILE , the *ENERGY FILE , and/or the *NODE FILE options must be used in conjunction with the *FILE OUTPUT option. These are the current coordinates if the large-displacement formulation is being used. 2 of the ABAQUS Analysis User's Manual. 0005 *Node Output, nset=Set-1 RF1, RF2, RF3, RM1, RM2, RM3 (Set-1 contains the reference point mentioned earlier) Jun 22, 2010 · The format of abaqus output file (ODB) is not text. dat) using the *node print input file keyword. An Abaqus model can be defined in terms of an assembly of part instances (see Assembly definition). Abaqus stores field output results sorted by the labels in ascending order. First coordinate of the node. By default, these values are displayed in the global coordinate system; you can choose to apply the nodal transformations to the results or to apply a user-specified coordinate system transformation. ABAQUS/CAE can calculate and report values for a given variable at a variety of positions. You can control the following types of printed output during the analysis run: element output, node output, contact surface output, energy output, fastener interaction output, modal output, section output, and radiation output—see “Output to the data and results In contrast to field output, which is associated with a frame, history output is associated with a step. Node-based field output variables are written to the output database at each node, along with any nodal transformations applied during model creation. To help locate nodes in the viewport, you may want to produce a model plot with node symbols visible before using the Query toolset. Products: ABAQUS/Standard ABAQUS/Explicit. The ‘node’ (which is probably named SPHERE-1. DAT output file with all node variables: ** ** FILED OUTPUT: H-Output-1 ** *Output, history, variable=PRESELECT *NODE PRINT, nset=yourNameSet COORD, NT You have to write it in the INPUT FILE (MODEL --> EDIT KEYWORDS) just before the *end. Give the identifying keys for the variables to be printed in a table for this node set. Input File Usage. If no node set is selected by using the NSET parameter (both for nodal and element values, since output in the . nn where nn is a number) is the reference node It may be necessary to leave blank data lines for some nodes if any other node in the model has more than seven temperature points because the total number of temperatures that Abaqus expects to read for any node is based on the maximum number of temperature values of all the nodes in the model. frd file is always at the nodes) output is for the complete model. 2) or as either field- or history-type output to the output database (. The value of N applies to *OUTPUT,*ELEMENT OUTPUT, *EL FILE, *ELPRINT, *NODE OUTPUT, *NODE FILE, *NODE PRINT, *FACE PRINT,*CONTACT OUTPUT, *CONTACT FILE and *CONTACT PRINT. Then, all nodes going from n 1 to n 2 in steps of i will be added to the set. The tables in this section list all of the output variables that are available in ABAQUS/Explicit. com contact output ncrementation o开tpt(只有 abaqus explicit） 输出到打印文件(*dat) Jul 23, 2011 · I found this command to force ABAQUS creating a . History output data are stored in the historyRegions repository under an OdbStep object. The keys are defined in the “Nodal variables” section of “ABAQUS/Standard output variable identifiers,” Section 4. The nodes do not need to be numbered continuously. The variables that are available consist of those you have saved to the output database for the current step and frame; this step and frame is identified at the top of the Report Field Output dialog box. If this parameter is included, each data line should give a first node, n 1; a last node; n 2; and the increment in node numbers between these nodes, i. 2, and “Node output” in “Output to the output database,” Section 4. If a local coordinate system is defined at a node (see Transformed coordinate systems), you can specify whether output to the data or results file of vector-valued quantities at these nodes is in the local or global system (see Specifying the directions for nodal output). The location of the results output is specified in the ABAQUS input file using the `POSITION = ' option on the `*EL FILE' command.

For nodal variables 1, 2, and 3 are global directions (1= X, 2= Y, and 3= Z; or for axisymmetric elements, 1= r and 2= z). You can request nodal variable output to the data, results, or output database file (see “Node output” in “Output to the data and results files,” Section 4. odb History: yes All physical displacement components, including rotations at nodes with rotational degrees of freedom (for output to the output database, only field-type output includes the rotations). ) to the output database. dat: yes . If this parameter and the NSET parameter are omitted, output will be written for all the nodes in the model. *Node Output COORD . Include this parameter to restrict output to only nodes that belong to the exterior three-dimensional elements. These output variables can be requested for output to the results (. In a geometrically linear step in Abaqus/Standard the relative position output variable does not change (in the same fashion that the nodal coordinates are output). This parameter applies only to Abaqus/Standard analyses. Oct 7, 2008 · Using ABAQUS/CAE, I need to extrapolate, as text file, the node coordinates on a face of my model. Set this parameter equal to the name of the node set for which this output request is being made. This page discusses: Selecting the Nodal Output Variables Define output database requests for nodal data. Activate/deactivate the check boxes in the tree on the Node Output tab to add/remove identifier keys in the table. You can choose to extrapolate the variables to the nodes and to then average them over all of the elements in the set that contribute to each node. Activate/deactivate the checkboxes in the tree on the Node File tab to add/remove identifier keys in the table. i must be an integer such that (n 2-n 1) / i is a whole number (not a fraction). 3). Averaging occurs Mar 29, 2018 · In Abaqus/Standard, you may print nodal and/or element output to the data file (. Node number. In Standard or Explicit, you may print to the results file (. NSET The output variables listed below are available in Abaqus/Standard. For this parameter, the output is 0 for every node, except the control node where the output is 12 in the z-direction, and 0 in the x and y directions. The same node (or node set) can appear in several output requests. This parameter applies only to Abaqus/Standard and Abaqus/Explicit analyses. GLOBAL Specify the identifying keys for the variables to be written to the output database. Abaqus creates keys to the historyRegions repository that describe the region; for example, 'Node PART-1-1. This interface program will transfer results at all ABAQUS positions except `REBAR'. Upvote 0 Downvote. This option is used to write nodal variables to the output database. In the Node Output tab, define *NODE OUTPUT for the selected Output block. SURFACE Nov 26, 2020 · The indexes are not node labels. 1. This parameter is valid only for nodes defined under BOND, and only the BONDSTAT and BONDLOAD output variables may be requested. For example, if two elements share a node, then NFORC can output the nodal forces at that node (of course zero because of balance) and the contribution from each element. If this line is omitted, no nodal output will be printed to the data file. The keys are defined in the “Nodal variables” portion of Abaqus/Standard output variable identifiers. The output in the . fil/. The CONTACT OUTPUT, ELEMENT OUTPUT, ENERGY OUTPUT, INCREMENTATION OUTPUT, MODAL OUTPUT, NODE OUTPUT, and/or RADIATION OUTPUT options can be used in conjunction with this option. The following parameters are supported: Nset, Frequency, Last mode, Global, and Mode. For Abaqus models defined in terms of an assembly of part instances (see Assembly definition), output in the data and results files is given in terms of node, element, set, and surface labels generated internally by Abaqus. The output will always be written to the results file at the last increment of each step unless FREQUENCY =0. In ABAQUS/Standard output quantities from eigenmodes, surfaces, fastener interactions, and sections can also be written to the data and results files. Repeat this data line as often as necessary: each line defines a table. 005 *incrementation output dt *energy output allke, allse, allwk *energy output, elset =small allpd *integrated output, surface =cross_section1 The node number must be a positive integer, and the maximum node number allowed is 999999999 (for information on integer input, see Input Syntax Rules). Set POSITION = AVERAGED AT NODES if the values being written are the averages of values extrapolated to the nodes of the elements in the set. odb) file to a formatted report. NSET. Set FORMAT = LABELS to specify that the output use the standard labeling format. By default, the report is printed in plain text format; however, you can also create reports in HTML and CSV (comma-separated values) formats. In such a model all nodes must belong to One of the following mutually exclusive parameters is required when the *NODE OUTPUT option is used in conjunction with the *OUTPUT, HISTORY option for Abaqus/Standard or Abaqus/Explicit: NSET Set this parameter equal to the name of the node set for which this output request is being made. First direction cosine of the normal at the node (optional). This is where Abaqus “History Output” becomes useful. Nset and Variable parameters are supported. If you only want the final results, choose N very big. I understand that ABAQUS interpolates or extrapolates from integration points to nodal points, so intuitively this tells me that my integration points are more accurate and to output variables at those points instead of nodes. POSITION. Probe annotations display the node's label and the results at the node for the current field output variable. How node-based field output results are computed. Energy output is available, as are output flags to identify whether a connector has failed (in Abaqus/Explicit only), locked, or reached a connector stop. I then output the nodal displacement (U), reaction forces (RF), concentrated forces (CF), and the element strains and stresses. I found also this one to print stress and displacement The output database report utility prints information from an Abaqus output database (. For nodes entered in a cylindrical or spherical system, this entry is an angle given in degrees. Would that be correct? I am interested in the maximum and minimum principal stresses as well as deflections. 1 of the ABAQUS Analysis User's Manual. In addition, the ABAQUS Scripting Interface examples, “Reading from an output database,” Section 3. By default, the nodal output to the output database is written using single precision, which may not be sufficient for certain classes of problems; for example, submodels undergoing large rigid body motions (consider also surface-based submodeling in these cases—see Surface-based submodeling). 2 Int Point 1' You can use the node and element sets created for tracer particles in the output database to control the display of tracer particles in the Visualization module of Abaqus/CAE. 例如： *output,history,op=new,frequency=1 *node output,nset=ends u,v,a *modal output gu,gv,ga bm, 其中， op=new表示清除先前定义的输出设置，并定义新的输出设置； frequency=1表示输出每个增量步的历史变量；*node output表示输出节点集合ends的 Give the identifying keys for the variables to be printed in a table for this node set. Set FREQUENCY =0 to suppress the output. for all elements or nodes in each time step? Thank you, Ardavan. The constituent names are appended to the output variables for output at the micro-level. Output quantities from the elements, nodes, and whole model can be written to the data and results files in ABAQUS/Standard and to the selected results file in ABAQUS/Explicit. fil: yes .
