Hi
I want to search on a fluid with variable properties, I used UDFs, but i have problem in initialize. I interpreted the following code with no error but as I wanted to initialize the project I faced an ERROR :

"the mesh component in mesh requires user input before it can be updated.for instruction on how to address the cell in its current state, click blue triangle in the lower right corner of the cell."

what is my mistake?


#my code:

#include "udf.h"
/* profile for density */
DEFINE_PROPERTY(Cell_density, c, t)
{
real rof;
real temp = C_T(c, t);
rof = 1130 * exp((-0.0004173)*temp);

return rof;
}
