Default Heat flux UDF problem
Posts: n/a

I have a 3D domain...which is bascially a partial clyinder cut at along the axis. I am trying to write a UDF for the heat profile over the top and bottom surface.The heat flux equations for the 2 surfaces are related to each other and are obtained by solving a set of non linear equations...for which i have written a newton raphson function. I call this function in the two F_profile macros for the heat fluxs....i interpret the udf...however on assigning it as the boundary condition gives me a Fatal error

The problem exists due to calling newton function in the macros...

If anybody has any clue on that....please help.

Hi Manan,

I have had similar problems when trying to assign certain UDFs. The problem occured for me when i assigned it to an interior zone. I changed it to a wall (coupled wall) and the problem didnt recurr

Good Luck
