External boundary conditions
 

Hi there,

I've been trying to simulate externatl temperature boundary conditions on chtMultiRegionFoam, but it doesn´t seem to be working properly. I've tryed with GroovyBc also, but nothing.

I'm trying to simulate how a foundry sand mold (T = 300K) with cast iron differential box inside (T = 1600K) losts temperature. Anyone knows how to set external boundary conditions properly? Taking into account that external temperature is also 300K (with fixedTemperature doesn't work).

Thank you for your attention!

Best regards
