Default error before iteration

Hi all, When I want to iterate the case an error message appears.

Error: Floating point error: invalid number

Error Object: ()

Has anybody an idea of what's the problem?

Error in boundary condition? For example, mass flow inlets can be set only in the positive x direction, which can cause Fluent to get confused.

Ok Allan I will revise all boundary conditions.

In fact, now I face with an other error message when I set the material propierties in a different case. It case uses an udf and when I try to impose an udf density for the mixture an error appears saying:

Set_material_property: null user defined function name

Does anyone know how to solve this?

Many thanks!!
