Hello,

I've got this error in OF 1.4 - simpleFoam with a case setup that worked in OF 1.3:

Can someone tell why it is asking for U, then phi, rho, gamma ... in the 0/p file?

Thank you,

Hello again,

Has anyone had this problem with OF 1.4 and simpleFoam - with this B.C.?

I don't understand why is it complaining about those entries in that file (0/p).

I repeat: the exactly same setup worked just fine in OF 1.3.

Anyone?

Thanks,

Ervin

Didn't anybody observe the above described behaviour of simpleFoam and rhoSimpleFoam (for those kind of B.C.)?
What changed from 1.3 to 1.4?
Am I making a mistake with the B.C. in OF 1.4?
