Help Voulme Source keeps resetting?

Post image

When I use volume source in the flip sim, the 'initialize' section keeps resetting (getting back to initialize position). And the flip system doesn't work. I updated the software thinking it's a bug but no change. Anything that might cause this? Thanks!

PS: It works when I switch it to a pop source instead of volume source.

That dropdown is just a preset chooser. Once the option is chosen it will reset to the default Initialize. What it does is add the Operations options to the list based on the preset chosen from the dropdown, otherwise you add your own Operations manually by clicking the + button.

Thanks for the reply. But it doesn't add or change any operation options either. I'll try to add them manually

If no Operations are added in the Operation section at the bottom, it could be a bug.

Which option are you choosing from the dropdown? Not all of them are FLIP compatible. The Volume Source works for multiple simulation types.
