ozgun Guest Posts: n/a	Hi, -Could anyone help me solve a set of stiff, initial value ODEs via udf? -Is there any way to use Fluent`s matrix solvers from udfs? -Is it possible to call an external numerical tool via udfs? -I tried system() and exec() functions but it seems as if such a coupling is not possible. Any suggestions ? thnx!
