Juzwa Posted March 20, 2015 Share Posted March 20, 2015 Hi, I know how to create a velocity field. But what about other fields? Eg I want to control my disturbace by a field. So this would be a scalar field. But I don't know what next. I probably need to assing some scalar values to it and keep them as some attribute? Or maybe just an SDF?

Hi Joseph, i made a simple example for you. I am controlling dissipiate to make it visual but you can easily control any field. Also you can create this field inside dops (create a new field use "gas geometry to sdf" or "sdf to fog") too. fieldMask.hipnc 1 Quote Link to comment Share on other sites More sharing options...
Rio.Dominia Posted April 5, 2015 Share Posted April 5, 2015 U can creat a field called speed . And use the gas match field to let the speed reference the density field . Then creat a gas analysis to analysis the lenght of the vel . So u can control the disturbace from speed field. Quote Link to comment Share on other sites More sharing options...
