melazoma Posted May 29, 2010 Share Posted May 29, 2010 Hi all, I remember hearing that the velocity field created by a fluid simulation can be used to move RBD objects in another sim. I've looked into the Force Field dop, but this dop takes geometry data with "force" attribute, instead of a vector field data like "vel" (as created by a fluid sim) Perhaps I can pass the vel data to a popnet first and advect some particles and use that motion to drive the RBDs. But is there a straight forward way to use the vel data in another RBD sim? Quote Link to comment Share on other sites More sharing options...

It just crossed my mind that there is a prebuilt asset for what i did in my file, the fluid force DOP. rbd_velField.hip Edited May 29, 2010 by mawi 1 Quote Link to comment Share on other sites More sharing options...

It just crossed my mind that there is a prebuilt asset for what i did in my file, the fluid force DOP. It works! Thanks a lot for the pointers. I was also looking for a way to import a bgeo-cached velocity field back into dops as a field force. A SOP Vector Field did it for me. A quick example is attached. moveRBDwFluid.hipnc 1 Quote Link to comment Share on other sites More sharing options...
