To import a user-defined function file, use the File/Import/UDF file menu item.

File → Import → UDF file

In the Choose a file panel, select the appropriate .UDF file and click OK. You will be prompted to specify the simulation where you want to store this UDF file.

Ansys Polyman will store the file in the Inputs subdirectory of the appropriate simulation subdirectory and create a leaf named filename.udf under Inputs in the relevant branch of the Simulation(s) section of the project tree.

The filename of imported UDF files must contain the character string udf. Examples of valid names include udf.clp, flow_udf.clp, and flow.udf.
