divergence in AMG solver
Hi im trying to use the following equation in udf. it does compile it but when i use it as a boundary condition for wall it says : error : divergence detected in AMG solver : x-momentum i use it for modeling slip flow on a half circle and the term [ (8*x*y/(D*D) ] is for 2*sin(a)*cos(a) where sin(a)=y/(D/2) , .... after omiting other terms and trying the other ones i found that the problem is the above term . can any body help me?
