Hey guys,

I am facing quite a similar issue as this post, I try to initialize my case file and it is ok with a "medium" mesh (with hexahedron cells of 5 microns length, 3,960,000 cells, mesh file of 273,276 kb) but I got the same error than fluidizedbed when trying to use cells of 3 microns (18,300,000 cells, mesh file of 1,726,340 kb)

My domain is 1.5 x 0.6 x 0.55 microns

I tried going from 1 GPGPU to 0 as advised on the post I linked above but it did not help. Not sure I full understand the link shared by Kareem. Does anybody have an other solution to solve this issue ?

FYI, I am using Fluent 2021R1 (but same issue with Fluent 2022 R2) on my Uni's HPC, Enterprise capability level, 3D, double precision set up

[UPDATE]

I've solved the issue, I was working connected to a node of our HPC but not using all of its memory. By increasing the memory usage, I've managed to initialize and run my job
