Hi all,

I'm trying to setup IGG-AutoGrid5(Turbo 181) to generate the mesh in parallel computing. Right now it only runs as a single process and uses one CPU core out of the 18, which makes it very slow for a 5 million node domain.

I use a Windows 10 system with admin rights.

I have used the Admin tool to setup all the MPI options, confirmed that they are running (through services.msc) and successfully registered the user as (COMPUTERNAME\UserName). I have also turned UAC off according to the documentation.

Does anyone know if I need to perform any additional steps, or is AutoGrid5 able to compute in parallel at all?
