How to calcl cell temperature

newminde · June 17, 2013, 06:46

Hay.
I want to ask how I can access data about single cell.
for example I want to use macro for cell C_T(c,t). The question is how to define cell index as pointer, if I want to calculate temperature at every iteration in {0.0025, 0.00025} cell coordinate.

The function

Code:

CX_Find_Cell_With_Point

could be what you required, however its prototype varies among FLUENT versions.

Since you only need to find the corresponding cell index and thread once for all, instead of the aforementioned function you could appeal to the brutal force. You could use

Code:

thread_loop_c

looping over the domain to pinpoint the cell and thread indices at some stage, say

Code:

DEFINE_EXECUTE_AFTER_CASE

then store such values in file scope variables for late use.
