Hello
Please please please help; I have been stuck here for weeks. I have installed the latest version of CFDEMCoupling_23.02 (couples LIGGGHTS-PFM with OF-6) in our university's Linux cluster. Compilation is done successfully without nay error.
Atm, I am running at the moment pure DEM simulation (LIGGGHTS) case in parallel wit 224 processor. The case starts successfully without any problem runs for a quite a while (1.5-1.6 sec) but all of a sudden (while insterting particles) it throws the error "realloc():invalid next size" and its getting killed. I am not able to understand what is this and how can I solve this issue. The error from output file looks like:
INFO: Particle insertion r_ins: inserted 133127 particle templates (mass 0.009986) at step 6000001
- a total of 798762 particle templates (mass 0.060041) inserted so far.
