Hi,
the problem is, I have a hermetic area, which is filled with water and air. The water should have a higher initial value than the air, whereupon a heat transfer takes place from water to air. To model this, I selected two materials: Water & Air. For the Physics Interfaces I selected 'Nonisothermal Laminar Flow', which combines 'Heat Transfer in Fluids & Laminar Flow'. Trying to simulate it produces an error that it didn't converged. Which settings I have to set for the heat transfer between these materials?
