Temperature gradient
How to obtain a temperature gradient directly from the solver for the UDF purposes? Does any macro exist to compute temperature gradient?

Re: Temperature gradient
C_T_G(c,t)[i] -- cell_t c, Thread *t, int i : gives you temperature gradient component.
C_T_G(c,t) -- cell_t c, Thread *t : gives you temperature gradient vector. |

Thanks very much for Your help!

Re: Temperature gradient
You may need to be careful when using these macros depending upon what you are doing with them. They are not generally applicable for calculating gradients at faces - ie for flux calculations. As far as I can work out they return the gradients between neighbouring cells in the specified direction.

Re: Temperature gradient
I just only want to check value of temperature gradient at my computational domain but when I use
C_UDMI(c,t,i)= C_T_G(c,t)[0]; my UDF is compiled correctly but Fluent send a SEGMENTATION VIOLATION error. What could be a reason of that? |
Re: Temperature gradient
Did you define sufficient space for your udm's??

Re: Temperature gradient
Yes, I defined u sufficient space for UDMI's...
My domain is axissymetric and I make: C_UDMI(c,t,0) = C_T_G(c,t)[0] for axial direction C_UDMI(c,t,1) = C_T_G(c,t)[1] for radial direction Is it correct? |
Re: Temperature gradient
hi i need to know the temperature gradient in the domain, i am using the using the udf... but i didnt know how to display the same, please do suggest me
