Set multiple processors in Windows cmd for TOUGH3 running

Hello TOUGH community.

I am using TOUGH3 after compiling the codes with Microsoft Visual Studio in Windows.

I can run the code with a single processor, but how can I set the multiple processors?

At cmd, I typed: set MPI_NUM_procs = 4, but I am not sure if 4 processors were used in the computation, because the element order in output_elem.csv is identical to the MESH ELEME order. (In the TOUGH3 manual, it says that if we use multiple processors, the output element order will be changed.)

    TOUGH3 does not run parallel under Windows. If you want to run parallel simulation, you may compile it under WSL (Windows subsystem for linux).

      Kenny Thank you for your answer. Is there any known maximum number of elements for Windows-complied TOUGH3?
