Hello,

Does anybody know if Fluent is able to determine a specific point, for example, I have a cylinder as a model and I'm wondering if Fluent can find the point which has the lowest temperature in a heat transfer problem, and give me the coordinates..

Thank you,

K.P

I think it can be easily implemented by UDF. Take a look at macro called DEFINE_ON_DEMAND in UDF guide.

Goodmorning Sixkillers
I read the DEFINE_ON_DEMAND in UDF guide and I used the example.. Unfortunatelly I am not familiar with C language, so for that example, I can only take the min and max of temperature and not the coordinates.. Am I doing it wrong or I have to do something more ??

You can use macro C_CENTROID to obtain centroid of each cell. Basically you need to iterate through all cells in your domain and save location (centroid) of a cell with min/max temperature and then print its location.
