System out of memory:

Error

Solver error: The system ran out of memory

What happened?

  • The simulation stopped as the solver memory requirements exceeded the machine memory.

What could be the possible reason?

  • The mesh size for the simulation is comparatively large and requires more memory than available on the selected number of cores.

What can I do now?

  • For the same mesh, increase the number of compute cores to increase the available memory for the solver. Recommended is at least 8 cores for intermediate mesh sizes (2-3 million cells) ,16 cores for large meshes (4-5 million cells) and 32 cores for very large meshes (6 million cells and onwards).
  • Optimize the mesh size or make it coarser so that less memory is required by the solver.
