Parall UDF

Dennis

Hello everybody,

I am having problem running a simple UDF in parallel. I posted the UDF here before: http://www.cfd-online.com/Forum/fluent.cgi?read=58256

#include "udf.h"

DEFINE_PROPERTY(cell_viscosity,c,t) {

real mu_lam;

Domain *domain;

domain = Get_Domain(3);

if (t == Lookup_Thread(domain,4)){

mu_lam = 10.; }

if (t == Lookup_Thread(domain,3)){

mu_lam = 20.; }

if (t == Lookup_Thread(domain,2)){

mu_lam = 30.; }

return mu_lam;

}

In single mode it works perfectly, but in parallel the viscosity doesn't change. I read the "parallel UDF usage" in the UDF manual but I still don't know what I have to change.

I hope anybody can help me. Thanks in advance

Greetings Dennis
