therazer is on a distinguished road
Hi all! Sorry for bad english.
So i have Rectangular paralleleriped. Bottom flate is heated to T=600K. Another plane`s T is 300K. Inside is an air.


Controldict and transportProperties are from example cavity (/run/tutorials/icoFoam/cavity/)
So i set Boundary conditions and generate mesh. What`s now? I think i need now fvSolve fvSchemes files. Plz help, i dont know what this files must contain.
