Hey guys

I'm new here and just started using OpenFOAM 2 weeks ago and am trying to understand it by doing tutorials, reading the user guide and forums. Till now everything was going well and I didn't have any problems. But as you can already see in the title I tried the motorBike tutorial and it doesn't seem to work properly.

I used the ./Allrun command but it was done running in less than a minute. And once I open it in paraview I just see the backgroundmesh. No motorbike, no velocity, nothing else to see.

So I wanted to ask you guys for help. I get error messages in paraview if I try to look at the deconstructed case and the time also stops at 1. The log files don't look good as well.

--------------------------------------------------------------------------
It looks like opal_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during opal_init; some of which are due to configuration or
environment problems. This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):

opal_shmem_base_select failed
--> Returned value -1 instead of OPAL_SUCCESS

I've attached some screenshots for you so you can maybe understand what I'm trying to say

You need to post the Allrun log if you need more help. It seems blockMesh ran, but not snappyHexMesh. What does log.snappyHexMesh say?

There is no Allrun log...Should there be one?

I posted the snappyHexMesh logfile in my previous post. It's the second code

My bad. Seems the problem is with your MPI configuration. Did you use system MPI to compile OF?

Try running the tutorial in serial (blockMesh; snappyHexMesh; simpleFoam) and see if it works.

To be honest I've never heard the term MPI before.
I used bash on Ubuntu on Windows to install OpenFOAM.

I'll try, just have to wait for my own project to finish meshing.
