USER_GETVAR for boundary

gera · June 1, 2017, 05:03

Dear experts,

could you please help me with USER_GETVAR function in CFX?
The function:
CALL USER_GETVAR('<VARIABLE_DESCRIPTION>',CRESLT, <pVAR>,CZ,DZ,IZ,LZ,RZ)
returns variables for whole domain. Is it possible to get a variable on a boundary of a domain in user subroutine during the computation?

Thank you!

Unfortunately, USER_GETVAR only returns variables for the same locale (group of elements, or vertices) as the original call.

What are you trying to achieve ?

Opaque, thank you for your reply.

I need to take variable on a certain surface in Fortran subroutine. For example, I need temperature on a wall (coupled heat exchange problem). Is there any way to do this?
