c_udsi
 

hi friends
what is different between c_udmi & c_udsi in energy eqn?

Hi
There's a big difference between UDS and UDM macros. UDS is a generic transport equation involves unsteady, diffusion, convection and source terms which can be used to model transport phenomena equations such as species transport, charge current transport and many others transport phenomena. UDM macro is used in UDF to store the value of a variable either to invoke in postprocessing or in a part of code to recall the variable.
