Hi,

when I am using renumberMesh -overwrite, it will change some of my BC parameters which is crucial.
For example I setup outlet boundary for nozzle as
type waveTransmissive;
gamma 1.4;
lInf 0.2
fieldInf uniform 101325;
value uniform 101325;

but after running renumberMesh it will change to
type waveTransmissive;
gamma 1.4;
value uniform 101325;

is any specific reason for that ?

Are you sure these two parameters are necessary to setup BC?

Hi Nima,

Yes it's necessary, but I think the problem was with "uniform" at fieldInf, after removing it, renumberMesh have not changed those parameters.

Thanks,
Ehsan

I think the problem is with the missing semi-colon ";" in the lInf line. This screws up the file reader. (You should also encouter problems with other utilities and solvers reading this file)
