Memory Utilization with Flow-3D
All
noticed that by using SMP version the CPU utilization is high (without GMO option turn on) but memory utilization is always low at around 200MB-400MB. so I wonder why the program didn't fully utilize the memory size that my system have (32GB RAM) in order to provide additional speed up in simulation time?Thanks. |

so can you advice what physic, solver setting & mesh size will allow full memory utilization? btw, should i expected simulation time speed up if the memory utilization is 100%? |

I don't think using more memory would speed up the simulation. memory is like a hard drive, a storage. Using 100% memory would mean you have 32 Gb for your computer to remember, which means your cpu would have more stuff to calculate.
If you use more cells (smaller cells), then your memory usage would go up, but the calculation time will be much longer I believe. |
