Top 7 FloTHERM V11 Features – #5: Overlapping Localized Grid
A grid (mesh) defines a tessellated collection of small volumes that cover the 3D volume of space that is to be simulated using CFD. The governing equations are integrated (discretized) over these volumes and solved iteratively until they those equations are satisfied. Out of the process comes predicted values of temperature, pressure, velocity etc. at each of those grid cells. … [Read more...]
