Use User-Defined Properties for a Surface

If desired, define the output using the User-Defined tab, which will allow you to specify the properties of the surface using user subroutines.

1. From the Connectivity tab, activate the User-defined properties option.
2. Click the Properties tab.
3. Enter the initial and final values in the U and V directions.
4. Click the User-Defined tab.
5. Define the user subroutine.
   1. Provide an expression with the USER solver function with parameters being passed to the user subroutine.
   2. Alternatively, activate the Use local file and function name check box to specify a local file where the subroutine code can be accessed by the solver.
      If this option is not specified, MotionSolve will search for a subroutine following its user subroutine loading rules.
   3. Select a function type from the drop-down menu.
   4. Select the local file for the subroutine.
      The type of file to be specified will depend on the selected function type. For example, if DLL/SO is selected, you can specify a file with a .dll extension (for Windows) or an .so extension (for Linux).
   5. Specify the function name in the subroutine that defines the entity, or accept the default name provided by MotionView.
