Simulation of a sample in a furnace w/ chtMultiRegionFoam
Hello to all,
I have been 6 months trying to get an understanding on OpenFOAM so I can do my thesis with it, but I am having so much trouble, please I could appreciate some help!
The case I want so simulate is conjugated heat transfer between a resin sample and a furnace. Between those two there is air.
Initial conditions are T=300K for the sample (mostra) and the air (aire_forn), the walls of the furnace are constantly at 473K.
There is no inlet/outlet, so I assumed initial conditions of 0 m/s for U.
I want to study Temperature, air flows and heat flows.
I have used the chtMultiRegionFoam as example, and all init. conditions and boundaries are defined via changeDict. I do not know if they are 100% correct though..
Mesh is done via the new multi-grading of OF 2.4 and I'm running UBUNTU 14.4.
CheckMesh is OK.
The last problem is when I try to run chtMultiRegionFoam and I get the following error:
Code:

Please, could you consider my case and give me advise?
All of you have been of great help when I was reading other posts! I would be very satisfied if I could learn more and become useful in the community to help others.
PD: Sorry for my bad English, you can also contact me at sergimart7@hotmail.com
Many thanks,
Sergi
