We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Compile the UDF and load it again. You may encounter an error when you try to recompile a UDF if your libudf is loaded into a case. In that case, go to Define → User-Defined → Functions → Manage Then unload the libudf and compile and load again. You can repeat this process also using TUI commands: /define/user-defined/compiled-functions unload “libudf” /define/user-defined/compiled-functions compile “libudf” yes “test.c” , /define/user-defined/compiled-functions load “libudf” For more information on this subject open ANSYS Help Viewer click on the Go To Page icon and enter the command help/fluug/x1-269000035.3.21.html#fluugUDFLibrary_Manager in the pop-up window then click on Go.
