Evaluation of Simtec
"I have worked on fire protection design in my fire consulting work. I have done some simulations using FDS and also helped with simulations using CFX. My experience is that the most common problems in the CFD models are the time required, geometry import and alignment of grid /mesh.
At present I perform the simulation with Simtec instead. I have discovered that geometry import in Simtec is incredibly quick and easy, and that the result is good. When architect has not produced a complete 3D Auto CAD model, it is easy to self-draw the model in the free program Sketchup and import into Simtec. To adjust grid /mesh of the model doesn’t require direct work. Simtec does.
