Improving Simulation Speed for Modified InterFOAM

gentodin · March 18, 2022, 04:45

Hi all,

I am currently running my Simulation and it takes really long.

I was wondering if there is any general thread lying around long ago regarding how to code your simulation in a faster way i.e. pointers/ memory reference reducing certain steps or simply deleting comments.

I wonder if there is a compiled general list regarding C++ coding to allow my machine to run it faster.

Also wonder if there is another list that is specific for solvers in OpenFOAM CFD.

Im running Interfoam and isnt sure if there is a way to increase simulation speed.

Regard,
S

Here is a suggestion:

I am happy to discuss further.
