cloudfx Posted September 29, 2011 Share Posted September 29, 2011 Hi, Trying to make a explosions with pyrosolver. Made the burnrate to be 1.5 to expand when the fuel burns and multiplied float number decreasing by time to freq and turbulence under turbulence tab to slow down as the fuel and expansion goes away. Even though I made the freq and turbulence to be really strong it does not catch the expansion speed. I tried to animation Scale under turbulence tab to be really strong at the first frames of expansion but it seems like it's going crazy when it's over 1.0. I tried step size under turbulence tab to be 0.2 from 0.05 when it expand but it does not work either.. What am I missing to give more strength of turbulence when it expand really fast?

bunker Posted September 30, 2011 Share Posted September 30, 2011 Simply map your turbulence where you have zero or little density. When your fluid expand, it will "collide" with the turbulent velocity. The gas release (divergence) is what's making your fluid expand, it is based on the burn field. you should team up with Glenn http://forums.odforce.net/index.php?/topic/14016-small-wall-explosion/ Quote Link to comment Share on other sites More sharing options...

I made the spline to be really strong for the beginning part but it seems like it still does not work to break up the shape when it explodes.. So I maybe have to lower burn rate and animate the gas release to make the explosion I guess. Thanks for the reply. Quote Link to comment Share on other sites More sharing options...
