I have a cloth object (for example Grid) and I want to pour FlipFluid on it to Affect Cloth.

I know that we should put FLIP Solver before Cloth Solver in the merge node in DopNetwork ,But in this case i take below error on the cloth solver :

Error : Object “flipfluidobject” the topology of the simulation geometry changed between frame times 0.4999 and 0.54166

I found “Cloth solvers interacting with other solvers” page in the Houdini's help or http://www.sidefx.com/docs/houdini12.5/cloth/interaction_solvers [sidefx.com]

and this page say : to fix it we should create and use “previous” attribute to save position of the fluid at the previous frame.

But i don't know how i can use this attribute and where i should create it ?!

:cry:

I'm having the same issue

I am trying to float a lily pad on water and have a frog be able to jump on it and have everything act accordingly. I can't figure out how to make the cloth lily pad float, and then stay buoyant above the water.
