Hi,
can anybody tell me if houdini supports staggered grids for 2d/3d eulerian fluid sims? I wasn't able to find anything like that.

Cheers,
David

I believe so. In dops you when you create a field you can specify where on the voxels to store the data using the Voxel Sampling parameter. It defaults to “center”, but in the smoke configure object the velocity field is set to “faces”, which I believe is the same as using a staggered grid.
