Decomposing mesh

Hello Foamers,
when I decompose my geometry meshed with SHM into 2 regions with the scotch method, there is something left out in the pressure boundary condition. I defined an outlet with totalPressure BC and specified gamma for the fluid. However, after decomposing the gamma is set to the default value 1. The same problem appears when I use mapFields and the patch only exists in the target geometry. Has anyone an idea what I might be doing wrong? Any help would be much appreciated. I am working with OF 4.1. Thanks! |

Found the solution! In order to specify a gamma > 1 you have to handle the fluid as supersonic compressible and therefore also specify psi (or thermo
 si) in the totalPressure BC as its default value is "none".
