Hello everyone,


I made a small geometry in salome. (figure attached below).


In this geometry, I made three groups (inlet, outlet and sideWalls).


And then I meshed this geometry in Salome and imported as a UNV file in Openfoam.


But when I model a kEpsilon Turbulence model through this region, It gives me the following error:

--> FOAM FATAL ERROR: 
Invalid wall function specification
    Patch type for patch sideWalls must be wall
    Current patch type is patch

After this error, I went to constant/polymesh/boundary, and changed the type of sideWalls from patch to wall.


But I don't know, that is it right to do like this manually OR is it possible to group the sideWalls as a wall type in salome itself?


because my solver is not converging after doing this and the values of k and Epsilon are going very very high. But I don't know the error is because of this patch type that I changed to wall manually OR I am making some mistake in modelling the Turbulent flow?


Can someone please help me out in this. I shall ve very thankful to you.


Thank you
