UDF to switch on energy equation each time step
 

Hi, guys, i want to realize auto switch on and off of energy equation each time step during unsteady case, and on every switchs thermal properity need to change, so what should i do?

And i also see some previous discussion about segregative solution of energy equation and momentum equations with udf or other methods?

PLZ, anyone's help is appreciated.
