Are Relaxation factors applicable to rhoCentralFoam?
 

in rhoCentralFoam there isn't relaxation factors in fvSolution at all.how can add these parameters?is it suitable adding the relaxation factors for a transient problem?

if just copy the lines from other cases it will be ok?

Did you find any answer for your question ?

Afaik, the solver must call the .relax() function to use relaxation factors. As rhoCentralFoam does not contain this function i'd guess that it is not designed to use relaxation.


Furthermore, i think it is of no use to underrelax the equations of an transient solver. You want to achive convergence of your simulation during runtime, not force it to become convergent.
