Perhaps this post may help? https://www.sidefx.com/forum/topic/50212/#post-226844 [www.sidefx.com]
I saw this post earlier, but this doesn`t help, in my case I scale fluid also, not only rotation and movement))

Problem with particles advected by volume April 30, 2020, 9:40 a.m.

Hi, I'm stuck with some difficulties when i transform volume cache by transform node and after that use in POP network through “popadvectbyvolumes”. Velocity after transform doesn't work right, so how I can transform properly this parameters in volumes?

Greetings, I deal with the same problem in a more basic level, I'm trying to fill a glass with water and I'm losing volume as you can see below
How many substeps is a good starting point?

Hello.If your collider is not moving at high speed, then you do not need to increase substep.
You need to decrease the Grid scale.
But if my geo collider moves definitely fast, I use pop fluid in basic pop solver, because flip doesn`t fit to this type of sim I think.



It can fit.The trick is to use transform instead of deformation, if your colliding body is rigid body motion instead of deformation
Can you share your scene?
