typo error

Posted February 23, 2017 at 06:03 by kindle

Q : Get very nasty output in the log when running in parallel ?
A : may be forgot the "-parallel" flag on the command line.
E : In stead of
Code:
mpirun -np 16 icoFoam -parallel > log
you trust your memory and write
Code:
mpirun -np 16 icoFoam > log
Then you will directly get the time directories of the whole domaine and there will be no time directionary in processor*. And in log, it seems that multiple processes are writing at the same time....

foam formation

Posted February 23, 2017 at 04:29 by kindle

When I heat the bowl to get warm milk, I got foam forming at the heating surface and the foam is staying at the inner surface after I drank all milk in it.

I'm trying to program a solver and its need a volscalarfield that initially must be zero everywhere in the mesh and I don't want to read it from any initial condition or to write it down. Anyone know how to do it?

thanks in advance Luis

However, I would like to view the average over say the last 100 steps, to view the statistics of the solution. Is there a way I can do this in paraFoam?

Also, how is convergence judged in this example? Normally I judge conversion in a
