Tips for dealing with resolution change

[pieforme]

Hi All,
So what's the best practice to upres simulations. I am having an issue here where we are working in about 2million voxels to get the settings right. But when we go to 12 million the sim is drastically different. Like in this one test the smoke went up instead of down.

Cheers

we just ended up simming in higher res. not ideal but couldnt really figure it out. Even between 30 million and 60 there is too much discrepancy. We are forming a logo so we have to be a bit precise.

Hello,

Indeed increasing the grid resolution will change the behavior of your simulation. In order to keep the shape and behavior it's best to use the resimulation method.

You can find more about it here - https://docs.chaosgroup.com/display/...e+Resimulation

I thought that was just for wavelet details, thanks for pointing that out.
