Adaptive grid threshold
#1
Hello
I'm struggling somewhat with this...whatever values I put into the threshold, the grid expands massively within a few frames. Even if I put it up to 99 and the velocity values are tiny, the grid just gets bigger. I look at the values using the numeric output, and they are in the range 0 to 2, yet the threshold seems not to ignore those voxels.
Any help appreciated, my sim times are going through the roof, even though there is nothing inside those voxels.

Thanks

Hello,

I'd say that some sim parameter is off the charts and generates extreme velocities, but can't tell.
You can try simulation with a Simple Source and see if the same happens.

Is there any chance I can send a scene for you to look at?
I simply cannot get the adaptive grid to work whatever I try.
I think I must be missing something fundamental.

Thanks

Hello,

Yes, please send the scene so we can examine it.

Thank you.

hmm I think I got this working...I scaled the fume grid down to .1. I think this was messing with the values, even though the sim itself was working.
I take it scaling the grid is a no no ?

Hello,

It would be very helpful to see the original scene to see what was the cause for this.

Thank you.
