I am trying to simulate a heat sink, very similar to the one shown in the tutorials... In spite of building a coarse mesh, the solution does'nt converge even after 2 hours of solving. I have an i5 processor and a 4 gb ram. I would like to know which solver and which configuration are best to solve my steady state heat transfer problem.
Thanking you,

Hi
CFD with only 4 Gb of RAM is a challenge, a too coarse mesh cannot resolve any turbulent behaviour, at least not in 3D, so there can be several reasons, such as mesh to coarse, mesh quality (boundary mesh ..) often its worth to use the analytical fprmulas for convecting coolign of horizontal or vertical boundaries, rahter to solve the heat convective equation fully in CFD mode

Good luck
