Dear community,
I’m running a pure granular DEM simulation and I got this error when I try to save the particle position under tecplot format. The number of particles is 226771 and the system has 32 Gb RAM. The initial file is saved (**_DES_DATA_0000.dat) but when it tries to save the next time step it crashes. vtp files are written normally.
Operating system error: Cannot allocate memory
Allocation would exceed memory limit
Error termination. Backtrace:
