Simulation exited with error

[CFLD]

Hi all,

I try to run the basic CFD tutorial 1 I found there http://www.opensim.co.za/training.html...
All well done following the tutorial...
But after solver starts, nothing happens (no convergence curves) untill this error message : "Simulation exited with error", few seconds later.

Pleeaase help !

Well,
Installation and dependencies seem ok.

The case runs fine on my system. It looks like it could be an MPI error. To confirm, you could try editing the properties of the 'CfdSolver' object and set 'Parallel' to false, and see if it runs. If so, try re-installing BlueCFD and make sure to install MSMPI.

Thank you,
it worked with "parallel" false so I uninstalled and reinstalled BlueCFD and MSMPI → works now !
Thank you again !
