I'm simulating an air-water bubbly flow in a vertical upward pipe using the interfacial area concentration model in fluent.
When I tried to define a nonuniform iac boundary profile (through udf or profile files), the typically "access violation" error occured.
And I am sure both of them are correct because they work well to define a nonuniform velocity boundary condition.
Furthermore, "access violation" error occured once the nonuniform iac profile is used. Only a constant input in the GUI is accepted.

Does anyone else encounter this situation? Help! Any advice is appreciated.
Sorry for my poor English.
