Hi,

I would like to know which solver to use with the following case : imagine the sample case of icoFoam, with which you impose a temperature at the top wall and a second different temperature at the bottom.
Many thanks in advance.

Thanks a lot. I will have a look to that case, and the example within those cases.

Regards,

Frédéric

I guess you can always add a thermal energy equation to icoFoam and call icoThermalFoam or something. That would be a nice addition.

I am guessing you are trying to solve the RB-convection kind of problems. If yes, I do have a code that solves the problem. Can pass it on iff you desire.

Hi Badri,

You offering a piece of code for RB-convection kind of problems. I would be very interstest in this piece.

Hi Badri,

I read your post few days ago. Since I am a new user, could you send me the files fvScheme and fvSolution that correspond to your RB code ? (in the solvers directory, as well as in the working directory)
Many thanks in advance. This is to be sure I am doing the right things.
Regards,

Fred

Hi Fred,
This is how the fvScheme and fvSolution looks like. This is really a rudimentary code though but since you are learning, this is a good start.
PS: I think these are the right ones.

Hi,

Sorry to be so borring, but the temperature is not a parameter that I can set up on a boundary.
In which file is it to declare ?
Thanks in advance,
Fred
