source term contours?

Magneto · July 18, 2012, 16:53

Hi Everyone,

I am using UDFs to add source terms to my domain. I would like to view contours of the source terms, which vary over the volume, in the same way Fluent lets you view velocity or pressure contours. Does anyone know how to do this?

Thanks a lot!

Activate a User-Defined_Memory Define/User Defined/Memory and fill it within your Define_Source-Macro using something like

C_UDMI(c,t,0) = source;

Contours of UDM can be post processed like any other variable.

cheers

Thanks! This is very helpful!

To do so do I have to use any specific define macro?
And what about compiling and hooking, just like tutorial shows?

I just stuck the command

C_UDMI(c,t,0) = source;

into my DEFINE_SOURCE macro where I calculate the source. This stores the source in user-defined memory location 0. Note that you have to allocate this memory before running the simulation (in the user-defined memory menu) or you will get an error.
