Difference between solvers
 

Is there any difference between chtMultiRegionSimpleFoam and chtMultiRegionFoam??
At this time im using the simplefoam,but I was figuring what implements i could get if I use the regionFoam.Any suggestions??

Greetings Gabriel,

If you check the User Guide, namely the section 3.5: http://www.openfoam.org/docs/user/standard-solvers.php
You'll see these descriptions:
As for getting started with the chtMultiRegion*Foam solvers, my advice is to study this tutorial: http://openfoamwiki.net/index.php/Ge..._-_planeWall2D

Best regards,
