How do I get the values for F_UDSI?
A UDS (User Defined Scalar) is used to solve scalar equations. When defining boundary conditions using a UDS, it is possible to give complex conditions using DEFINE_PROFILE and F_UDSI. However, the values given in DEFINE_PROFILE will not show up in post-processing functions (e.g.Display->Contours).
If you want the values to be displayed, you can use C_UDMI(F_C0(f, t), THREAD_T0(t), 0) to store them and have them available for post-processing. You cannot use F_UDSI.
Please note that because you are using C_UDMI instead of F_UDSI, you will need to check off Node Value in the options from the Contour panel. As this is for accessing face variables applicable for boundary or wall zones.
