i am trying to learn Houdini FLIP fluids, but i have the following issue:
I have a normal fluid sim, DOP network contains Flip Solver node with a connected SOP Solver node to the Input 2. I do some regular SOP ops, in the solver and it works, but the following problems are slowing my learning process
Almost all nodes, when i run a simulation, it is cached and i can inspect data on individual nodes. But that is not true inside this SOP solver. I see invalid network( nodes with red/white stripes indicationg some error, middle button inspect shows empty geometry in “dop_network” node. sometimes, i get correct view on frame 1, but i can't see what happens exactly during the whole sim. I hope that the issue is clear…
Hm, that seems to work for me. Sometimes I get a warning saying: Warning: Old geometry fetched since simulation is disabled. No DOP object names specified.
But it was never an error. Maybe I'm not reproducing your exact setup?
thanks for Your effort. I found that it is invalid (empty geometry) when the sim is stopped before the end frame by ESC. I can inspect simulated frames, but the issue is there. If it runs to the end, i have only the same warning…
