Data access problems can occur when you use a UDF created for a 3D model with a 2D model. A good practice is to code the UDF for both 2D and 3D. This can be done by using an if statement with RP_2D to distinguish a 2D model and RP_3D for a 3D model. Also, the Fluent utility macros ND, NV etc. can allow the user to create a UDF without specifying 2D or 3D.
