User Defined function for scalar gradient caculation with Star ccm+ V4
 

Hi all!

I m modeling flow and heat transfer in a heat exchanger model. After convergence of a simulation (or even during the simulation), i would like to caculate the temperature gradient at any point of the computational domain. I have tried to have a look at the User guide for the implementation of user Fortran code into Star CCM+ but the examples found concern only very simple user profile codes.

Could anyone help me please?

Sorry!

I found a solution! I was using an old version of the software! After updating to the new release (5.04), i found many derivative operators!

Regards!

how do you realize it?
 

can you tell me how did you adapt the derivative operator in the STAR-CCM+?
thank you very much, my email is 54acan@gmail.com

The field function "grad($Temperature)" provides you the gradient vector of temperature for your given coordinate system.
If you are just interested in the magnitude value of the gradient vector just use "mag(grad($temperature))".

I want to take dot product of gradient operator and unit normal vectopr for this i need to take just gradient operator so is it like "grad" only or $$grad please help?

thanks
