Hello, I came across while solving for a transient case under parallel processing in CFX and its resulting in a memory allocation error. I've referred and tried links and suggestions came across this forum and Youtube to overcome it but I was unsuccessful. Also, can anyone explain what is term WORDS in mentioned for memory spaces.

My PC Specs:
Processor: Intel(R) Core(TM) i7-10700
RAM: 48GB
storage available: 150GB

Does the error occur during interpolation, partiioning or solving?

It looks like it occurs during the partitioner. In that case, simply increase the real stack size for the partitioner as it says - this can be done in solver manager under advanced options, and set it to maybe 1.2 (or if you have lots of spare memory 2.0).

During Partitioning (i guess), i.e after allocation of processors and starting the solver.

Thank you for replying, I've tried this after reading in many forums but the problem isn't solved.

Please post the error message after you increased the memory, and you can also post the memory allocation section under EXECUTION CONTROL.

Something seems off.
