hello,

simulating eg water, we have several fields, for example a collision or surface. How can I get to these fields to turn them into geomagnetics and be able to use them ???

Thank you for your help.

Not sure what you mean by geomagnetics but if you need a surface for it/them you can use the Convert Volume SOP to get one.

Or if you need to move volume data into an existing set of geometry points you can use the Attribute from Volume SOP.
