Dimension problem rhoPisoFoam
 
Hi all,

i am new to OF and have a dimension problem when i want to solve a turbulent, compressible case.

So what dimensions should alphaSgs, muSgs, nuSgs, and nuTilda have?
I would be also pleased if anyone can tell me anything about these variables, for example their expression in equations like navier-stokes,...

thanks!

i solved this problem by editing the p dimension to [1 -1 -2 0 0 0 0]

Ive forgot that ive copied the files out of an incompressible case:)

Yes. From what I have experienced so far, the best practice scientifically and in terms of programming is to write down all equations your solver uses and see if the units are all the same.
