pyroevil Posted November 9, 2017 Share Posted November 9, 2017 (edited) Hi, I search and read a lot of post on google/ODForce without really finding a answer to that. I trying to see how I can compress a fluid correctly. Just to illustrate one case from many others , I try to compress gas with a piston in to a cylinder. I know Houdini is more a artistic tool than a fluid analysis software but there a way to make divergence, density and pressure interact correctly ... or what I thinking is a correct bihavior? In the example hipfile I attach to this post , I expect to see the density and pressure increased proportionnally to the changed volume of the cylinder by the pushing piston (SIM_Compress geometry at obj level). I figured out a lot of way to connect , inject , add , multiply combinations of density/divergence source without any good result ( "best" one attached to the post ). Somebody have a idea ? Thanks compression_test_v001.hip Edited November 10, 2017 by pyroevil Quote Link to comment Share on other sites More sharing options...
