Error with resuming EDEM-Fluent simulation
I am currently running a coupled simulation and encountered the following error after reaching 0.0347s of Flow time.
Advancing DPM injections .... Setting forces and torques on 273 (of 646) EDEM particles... Done. terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc ============================================================================== Node 999999: Process 5774: Received signal SIGIOT. ==============================================================================
To resume the simulation, I rolled back EDEM and Fluent to the last common saved timestamp: 0.034s. However, when trying to resume the coupled simulation, I encounter this error.
Advancing DPM injections .... Getting particle data from EDEM... Host sending injections to compute nodes. ============================================================================== Node 0: Process 86644: Received signal SIGSEGV. ============================================================================== ===============Message from the Cortex Process================================ Fatal error in one of the compute processes. ==============================================================================
This error continues even if EDEM and Fluent are rolled back to a previous timestamp (0.033s). I have tried moving EDEM one timestep back and coupling with Fluent to resolve this as well but it was not successful.
I have verified that both programs are able to resume their simulations independently. I am still unsure what caused this error. At this point, it seems like the only possible way solution is to re-run the simulations from timestep 0s. However, this is undesirable as the simulations took many days to achieve the current progress. As such, I would like to seek guidance on how to resolve this or if there is any other way to resolve this.
I have included some details of the system below.
OS: CentOS7 Version of EDEM installed: EDEM 2022.1 Version of Fluent installed: 22.1 and 21.1 Installation Location: Remote HPC server with both EDEM and Fluent installed
Thank you
