Dear Ed, If you can provide a little more information on the issue you’re having here, that would be great. Presumably you’re running Windows 10 x64? Are you using Visual Studio 2019? Can you confirm the version of Microsoft MPI that you’ve installed. Can you provide the command that you’re running in the terminal and the start of the output from the IncNavierStokesSolver run (the header information that’s displayed up to the point where it starts printing step information would be fine). In the CMake output that you see on configuration, can you see that it is actually discovering Microsoft MPI? Thanks, Jeremy

Dear users,
I am trying to run Nektar on Windows using MPI and I am following the instructions in the blog post of May 18 2020.
I find that the code builds successfully and it runs the example (cyl.xml) using multiple threads but it looks like multiple copies of the same work are being run, rather than a single (faster) multi-threaded simulation.
I wonder if anyone has experienced the same issue, or has any advice on how to fix this? Could it be some kind of MPI version conflict (I imagine the `multiple copies' is the default behaviour if MPI is not working)?
Thanks,
Ed Threlfall. _______________________________________________ Nektar-users mailing list Nektar-users@imperial.ac.uk https://mailman.ic.ac.uk/mailman/listinfo/nektar-users
