How do I resolve the error due to large number of particles during PiC simulation

During the execution of a Computational Fluid Dynamics (CFD) simulation utilizing the Particle-in-Cell (PIC) model in MFIX, an issue arose pertaining to the processing of a large number of particles. Specifically, the MFIX software exhibited an error, indicating an inability to handle the desired quantity of particles.

Please provide additional details: How many particles/parcels? What computational resources are you using? Are you running in serial or parallel?

The system comprises approximately 346,291 particles and 200 parcels. The simulation is being run on a single workstation with 8GB of RAM, using a serial computation approach.
