How to make sure that flux is doing parallel computing?

Hello,

I am running a 2D transient simulation in my desktop computer. I set the parallel computing option to use the 4 physical cores of my CPU but when I open the task manager I get the CPU performance as shown in the image below

Is that an expected output, or the CPU should be working harder? Is there an additional configuration to be done to run flux in the parallel computing mode?

Thank you in advance,

Matias

    Hi Matias,

    When you looking at the CPU performance, what are you doing with Flux ?

    All the define CPUs will used by Flux during 3D mesh or the solving part (during the linear solving process with MUMPS

    Hi Matias,

    What are you doing with Flux during the CPU performance check?

    Flux parallelization is done on a part of the software (3D mesh, linear system resolution).
