SolidWorks Simulation Database Files Description – Irfan Zardadkhan – PhD, CSWE

For SolidWorks Simulation Files, the results are contained in one file with the extension CWR. Other information like study properties, materials, restraints, loads, and contact conditions are saved, in the SolidWorks part or assembly document. Many files are created by the solver during an analysis. Some of them are temporary files automatically deleted when the analysis is complete, others are result files which are meant to be put together and saved in the CWR file before being deleted when the model is closed. In case of abrupt termination of the solver or of SolidWorks, the deletion of the files will not take place, leaving many unnecessary files behind. They can be deleted manually, as only the CWR file is required to access the mesh and results.

SolidWorks Simulation Database Files and their Description

.GEN This is the general information file that contains all information about the FEM database. Typically it would contain the coordinate system info, information on nodes and elements (mesh information), element groups, real constant sets, material property sets etc. This is like an input file to the analysis modules. Note that even if you delete the .GEN file you will have all the Material properties, Loads/BC, Mesh Control information (these information are stored as 3rd party attributes in SolidWorks part/assembly file database) intact in your study but your mesh data will be lost.

.MAS This is MS Access file that contains info about the entire database. This is also referred to as a master file.

.OUT This is a text file containing the solver info such as summarized displacements, stresses, etc. You can open this file in Notepad and read its contents.

.TEM This is a text file containing thermal analysis info, and a summary of the thermal results.. You can open this file in Notepad and read its contents. This file is the equivalent of the .OUT file for thermal analysis.

.LCD, .LCN, LCP, LCM These files contain the displacements results.

.IDA This is a binary file containing the equation number for each degree of freedom.

.LDS This is a binary file PRE1 (pre-analysis module) prepares, which contains load info.

.STE, .STN This file contains all the element and nodal stresses (STE for linear and STN for nonlinear analyses)

.FTR This is a binary file containing fatigue results

.STP This is a binary file containing Drop Test stress info for post.

.GCF This is a binary file containing contact info for post.

.ELF This is a binary file containing element forces

.EFF This is a binary file containing element forces for reaction force calculation

.CNT This file contains the contact force information, the remote forces (at interface surface) and Pin and Bolt forces

.NP1 This is a binary file containing plastic (and other types of nonlinear material models) elemental info for Nonlinear

.NP2 This is a binary file containing plastic (and other types of nonlinear material models) elemental info for Nonlinear

.MSF This is a binary file containing Frequency analysis information required for Dynamic analysis

.EIG This is a binary file containing Eigenfunctions (values and vectors)

.DSP This is a binary file prepared by PRE1 containing prescribed displacements

.RSL This is a binary file containing the result info from FFEPlus solver

In addition to the above-mentioned files, some other temporary files may be created during the meshing and solving phase in the work directory or the temp directory and should be automatically deleted once the process is completed.
