A fatal signal received after initializing a case with UDF

    • Yanyao

      Hi community, 

      I'm very new to fluent and UDF. Right now I'm working on a UDF, which is modified from 3D version to implement dynamic contact angle to wall adhesion. I think the compiling and loading is successful, however, after I click initialize I reveived following notice:

      Error:  received a fatal signal (Segmentation fault).

      Error Object: #f

      The case is 2d, dp, pressure-based, VOF, laminar, transient case, and it runs good without the UDF. I have attached my code here, any help will be greatly appreciated!

      You need to completely restrict the UDF to 2D analysis. Look into Macros for Dealing with Two and Three Dimension of the customization manual to check RP_2D and RP_3D.
