Mudslide in a landscape

Postby stevester1 » Thu Oct 12, 2006 10:15 pm

wow thanks alot, geez lol, 1.9 million particles haha, thats insane.
by the way, when it comes to density and int/ext pressure, how does that react when youre playing with values, because after seen the digital tutors realflow dvd (great purchase by the way, you guys should check it out), the animator uses density of 20-30 and int./ext. pressure of 0.0001 . Recently I've been using these values and all has been going well, what do you guys think?

it all depends on what you want for your fluid.
the way i see it, your int/ext pressure determines off course the pressure and thereby how violently the fluid is gonna splash around. if it for example is set to 0.001 there are no pressure to push the particles around and you get a more stable and calm fluid. this is were lower density values can play in, cause now your fluid need not to be as heavy as with a density of 1000. you can easily make it lighter to 200 or perhaps lower. it all depends on slow/fast you want your fluid to be. the good thing about this is that when your scene scale is bigger than it optimally should be, you can tone down the splashes of the fluid by setting the int/ext and density values, and thereby get a far more realistic result without having to drop the scene scale to rediciously low number.
