Pyro Explosion - Division Size Problem


LaszloFX

Recommended Posts

Hey Guys,

I'm working on a helicopter explosion with Pyro Simulation. It was created with the Explosion shelf tool and I changed some shaping parameters, mostly changed stuff in the fireball shader.

I ran into some weird problems. As I was working in fairly low res (under 10 million voxels), I got to a point where I liked the overall feel and shape of my explosion.

After I was trying to decrease the division size on my smoke object to get more details (under 0.05), my explosion sim started behaving weirdly. After a certain number of frames my explosion stops rising and my density stucks in one position. I won't grow further.

Based on the Houdini documentation, division size shouldn't change drastically the overall simulation, right?

Or is there any rules on how far you can go with your uniform divisions in your voxel grid?

Thanks in advance for any help!

Best,

Laszlo

Thank you for the quick and great reply Marty!

I tried Upres, and it's just what I needed!

I thought that after Houdini 11, Upres became irrelevant, but it turned out to be quite useful in this case :)

Thanks again!
