Storing and Retrieving FEA Results
By default, Creo Simulate stores all the analysis output files in the study directory named after the selected analysis. The study directory and all the output files, except for the model snapshot, use the same base name as the selected analysis. Note that if you select more than one analysis at a time, you are prompted to specify the name of the study directory.
If you set the fem_study_directory configuration option to no, Creo Simulate stores the output files in the current working directory. In this case, Creo Simulate names the output file as model.frd, where model is the name of your model.
After an FEA program has successfully solved a FEM part or assembly, the system stores both the model's mesh data and FEA results in a single database file with the name model.frd. This occurs regardless of whether you solved the model online or in the background.
To avoid re-meshing or re-solving the model, you can use the Home > Run > Open FEM Results command to retrieve the .frd file. The system retrieves the model and puts you in the system environment corresponding to the state captured in the .frd file. Thus, if you retrieve the file with FEA program results, you automatically enter the postprocessor.
When you store or retrieve the .frd file, keep the following in mind:
If more than one analysis is available, you can select a different analysis for your model and send it to the solver. When you click OK on the Run FEM Analysis dialog box and the system detects an .frd file that already contains solution results, the system prompts you to decide whether or not to overwrite the existing results.
If you select Yes, the system runs the analysis and stores the results in the present .frd file.
If you select No, the system prompts for the name of the file where you want to store the new results. Thus, the original .frd file remains intact.
You can only retrieve an .frd file that contains results.
You can only retrieve a stored mesh and results file that corresponds to the current model in session. If the system detects that you modified the model, it warns you that the model does not correspond to the stored mesh and terminates the retrieval process. Creo Simulate only allows changes to the model that do not cause changes in the mesh. For example, changing the value of a pressure load is acceptable, but adding or deleting a hard point or a force is not.
