patching-initial temperature
hey all,
im having some trouble with patching. I have a rectangular domain, at which I want to define initial temperature 30 degrees C at the upper boundary, 20 degrees C at the lower boundary and I want the temperature to linearly decrease from 30 to 20 at the points inbetween. Can anyone help please?? Any suggestions would be greatly appreciated! regards, Louisa |
rephrase of the above
hey,
I thought my problem is explained better this way: im having some trouble with patching. I have a rectangular domain, at which I define backflow temperature 30 degrees C at the upper boundary, 20 degrees C at the lower boundary and I want the initial temperature to linearly decrease from 30 to 20 at the points inbetween. The fluid enters the domain from a "hole" and is at 15 degrees C initially. At the initial conditions, i put 15C? Then how can I make the initial temp of the domain (porous media) to decrease linearly? Can anyone help please?? Any suggestions would be greatly appreciated! regards, Louisa |
Re: rephrase of the above
Setting spatially varying initial temperatures is simple via an udf. Look in the udf manual for the section and example dealing with initial conditions.
