 February 16, 2006, 05:18 Re: Depth varying in 2DH #4 Mick Guest   Posts: n/a You could use lots of blocks to make stairs

 February 16, 2006, 11:59 Re: Depth varying in 2DH #6 Mick Guest   Posts: n/a Perhaps I misunderstand you? 1/ You can make a solid volume STL file and import this onto a cartesian grid using the PARSOL cut-cell method to cut this object shape from the background grid. or 2/ Use a Body fitted grid or 3/ Represent the depth varying through blocking out a cartesian domain with object shapes from the library of such objects, wedges, rectangles, arcs, whatever.

With porosity fields ive simulated bumps or obstacles for inducing an hydraulic jump.
