Thermal energy in a cavaty flowI am new to OpenFoam and I have the following situation:
i need to simulate the convection/diffusion problem with: u=1, v=0, T_West=0 T_East=1 and dT/dy=0 for North and South I need to determine the rate of convergence of the numerical solution using the OpenFoam finite volume scheme. I just figured out how to add the temperature to IcoFoam. But I have to plot the the log(err) vs. log(sqrt(n)) when using n total triangules in 2D since sqrt(n) is a measure of the grid space. I was wondering if someone can help me with this... :) |
