I'm having difficulty with the yPlusRAS -compressible command in foam-extend-3.1. When using the mutkWallFunction, the utility does not recognise this as a valid option for the mut field and outputs zero value for yPlus on the wall. I cannot find any different in the execution of the code between OF230 and FE31, and so I wonder if it's not a dependency call issue.

Two questions:

1) What's the different between mutkWallFunction and mutWallFunction? Are they interchangeable without any significant effect?

2) Does anyone know a simple solution to fix the yPlusRAS utility to recognise all included wall functions?

Cheers
