Is there a free/inexpensive, relatively easy to use three dimensional FEM flow program that hydraulic structures can be modeled?
What 3D FEM programs are commonly used?
thanks, Dik

Hec-Ras is the most widely accepted hydraulic modelling software in north america. You can download at the following site

Hope this helps.

I was looking for hydraulic modelling, not stress analysis. Any suggestions?

Well, you're generally correct there. (I should have checked specifics before posting). GETM is listed and, obliquely, so is CCHE3D (NCCHE). For geomorphologic studies, you might consider the MD_SWMS (Multidimensional Surface-Water Modeling System) from USGS. I think you may actually be referring to what is commonly termed CFD (Computational Fluid Dynamics) rather than FEM (Finite Element Modeling). Check out "http://www.cfd-online.com". OpenFlower, OpenFOAM, Gerris Flow Solver, OpenFVM are examples of free CFD codes, but generally not with much more than a basic pre and post processor, if that. Fluent from ANSYS and FLOW-3D from Flow Science are two commonly used commercial codes. Some other ones are freely available from NASA and USACE (US citizens only, I think). But, this stuff is pretty complicated for the uninitiated. Most folks need graduate engineering mathematics and modeling coursework to successfully undertake CFD modeling work with these systems and - even then - the process can be quite time consuming. Beyond that, your simulation might simply be incorrect! CFD is not something that 99.999% of engineers would pursue (or need to pursue) - that's 1 in 100,000!
