Memory Management - how to reduce size of result files

loomings

Hi everyone.

Could someone share some tips on how to reduce the size of the files generated when doing an analysis in salome_meca?

A simple linear elastic example of a cantilever beam I did using salome_meca on Windows occupies 130 MB, which is way more than same analysis using abaqus or prepomax.

It seems to be mostly in glob.1 file.
Maybe I'm selecting too much data for the results? Or maybe I should delete this file after the run finishes? What would be the best practices for this?

I'm learning to use salome_meca, little by little, following tutorials in youtube. These tutorials normally do not discuss the aspect of memory management.

Below I leave some information:

.hdf file: 790 KB
.rmed file: 2236 KB

RunCase folder files:
_ExportedFromSalomeObject_0_1_2_5.med --> 508 KB

RunCase/Result-Stage_1/base-stage1/ folder files:
glob.1 --> 127 MB

Hi loomings,
The file glob.1 is useful only if you plan to run another simulation based on the results obtained in the first run, otherwise it may be deleted.
Did you set up correctly the output with the command IMPR_RESU? There you should be able to select only the fields that you need.
Furthermore, if you want to reduce the timestep between outputs without modifying the solution timestep, you may use the keyword ARCHIVAGE inside the analysis procedure.

For all these details and more, I strongly recommend to read thoroughly the two books by Jean Pierre Aubry that you can find on his website:
