UDS – Execution Failed

      Hi, I am working on extracting Mean Vorticity Magnitude from Fluent using UDS. The UDS was initially created using Fluent 19.2, but when I tried to execute the same UDS on Fluen 2020 R2, I ended up with SIGSEGV errors. Not sure what is wrong with the UDS. Please find the Screenshot of the UDS as shown below.

      Thank you,
      Best regards,
      Kushal

      Comment out sections to see what's causing the problem. Are you stopping the solver clearing memory (gradients etc) at the end of the iteration, and have you checked the macros are in the current code?

      Hi Rob,

      Thanks for the swift response,

      I compared the code against the newer version with the help of the customisation guide. However, Scalar_Derivatives is something I couldn't find in this version. 

      I am not sure how to flush memory from TUI.

      You want the TUI command from just above Table 3.11 and Section 3.2.11.3
