GOM File Generation Issues for Large Mesh Models

[JeanLPB]

Dear community,

I'm encountering some issues generating the calculation files (Anura3D_2024.gid) using the problem type in GiD Simulation 17.0.1.

I have successfully run the simulations for the models presented in the tutorial, as well as a few other case studies in parallel. However, when trying to scale up to larger problems—specifically, those with more refined meshes or greater dimensions, leading to a higher number of nodes, elements, and material points—I can no longer generate the calculation files using the original scripts. In particular, the GOM file has been generated either empty or with missing data.

From my analysis so far, it seems that this issue with exporting/generating calculation files for problems with a high number of nodes/elements is related to the computer's memory reaching its storage limit during the file generation process. I made some simple modifications to the "createGOM.tcl" script to initially reduce data storage (by processing in blocks and deallocating some variables), and I noticed that this allowed the GOM file to be generated with more complete data. However, I don't have enough expertise to fully update the script to resolve this issue and ensure that the complete file is generated without affecting the subsequent execution of the calculations.

I would like to know if this is a common limitation that others face with the current code, if it’s an issue unique to my situation, and if there are any existing solutions.
