Copy solution setup and Boundary Conditions from a case file

nonstopthinker · October 5, 2016, 02:32

Hello All..

So i am trying to model rectangular coolant channels in 3d and i am applying boundary conditions and solution methods. In one of the cases I have got the converged solution. Now i want to copy the same setup and boundary conditions to another channel (different width and height - different aspect ratio). Kindly help as to how i can proceed with the same. I have tried using the write-bc, read-bc commands, but it still does not run properly on the new case. Kindly help.

Thank you.

Try write-settings! It is very similar to the write-bc commands though so you might encounter the same issue.

If everything else is the same, this is an extremely helpful command. But it requires that all surfaces are named the same, etc, etc. You might have to do some manual stuff first like making interfaces, etc.

Really what you need is a journal file that contains everything you did on case 1 and use it for case 2, but that's probably not the problem! I usually tinker with the new mesh just enough so that the settings file can be read over.
