Hello Peter

There is a problem with the model. When I try to run it it gives a limitations error because i am using a student version. I have tried to make a command file but I dont know if its correct since i am not familar with APDL codes

the data which needs to be transmitted through this command file is 


Density= 1000kg/m3

Inlet Velocity= 1kg/s

Inlet temperature=20 C

I dont know about the convective heat transfer coefficient. i can assume the worst case scenario. 

I need to know how to define the inlet mass flow though APDL coding

and how to assign the convective heat transfer coefficient say 50 W/mm2C

I have  attached the model for you to see. Please take a look at the command file in the model.
