LeauRat Posted August 2, 2017 Share Posted August 2, 2017 Hi ! I did a water simulation with houdini 16. I create a source volume for my sphere to add after the velocity with a source volume in the DOPNetwork. It's working. But my problem it's the visualization. When I increase my resolution we can see the pattern of the velocity * plane * This plane come to the source volume velocity. I just want to break this shape. I just want a vel follow my initial shape * my sphere* and do not a plane or cube. So if someone can help me Thank you ! Quote Link to comment Share on other sites More sharing options...
vtrvtr Posted August 2, 2017 Share Posted August 2, 2017 When you add velocity in that add velocity field, it's adding velocity to the container, hence the look. If you want only in the mesh, add a v attribute with a wrangles before transforming into a fluid and source from that. Alternatively you can add mask the velocity inside the dop But just to be clear, even if you do that, the field will be square-ish, it's just that it will be zero'd in the area there has no geo Check attached square_vel_odf.hip Quote Link to comment Share on other sites More sharing options...

LeauRat Posted August 2, 2017 Author Share Posted August 2, 2017 Other question. If want add some noise in the vel and keep the shape of my object ? Need to set that before or after the fluid source ? Quote Link to comment Share on other sites More sharing options...
vtrvtr Posted August 2, 2017 Share Posted August 2, 2017 You can setup either way, however, usually working with points is easier than working with volumes IMO, so personally I would set up before. If setup in the fluid source, you'll need to mask it again to avoid the problem you're having to begin with Quote Link to comment Share on other sites More sharing options...
