Ansa (http://www.beta-cae.gr/ansa.htm) is a great tool for creating windflow-meshes around buildings. 90% of Workload is fixing Autocad mistakes, object simplification, and stuff like that. Gmsh is not really designed for that.
However, for simple models, gmsh is superior, as the learning curve is much better. Also, if you have a good cluster and want to trade of computation time from manual time, spider is an option: http://www.meshing.at/Spiderhome/Home.html it does automatic geometry simplification, but can currently only handle one air volume . Meshes are not that cute, but hey, more coffee-time... We do building flows on a regular basis, meshsizes of 20 million cells, with an enviromental radius of up to 1000m including all neighboring buildings... ----------------------------------- Bernhard Kubicek Energy Department Electric Energy Systems Bitte beachten Sie unsere neuen Kontaktdaten!

Does it have a limit on the number of cell? What file format can be imported? Many thanks Best Regards Antonella ________________________________ La tua privacy è al sicuro con Internet Explorer 8.
