Hi Rob,

Thank you for your answer. I was able to read the link you provided in Fluent. 

Regarding the definition of A, I realized the following:

  • the UDF example you provided defines A as: real A[3]
  • my UDF defines it as: real NV_VEC(A)

I am not sure if this is the issue (would it make a difference?).

If that is indeed the issue, I replaced the definition to "real A[3]" but I again receive the segmentation fault error.

Thank you!
