Blender Version
Broken: version: 2.82 (sub 7), branch: master, commit date: 2020-02-12 16:20, hash:
77d23b0bd7
Worked: version 2.82 beta (daily build from 2020-01-21, Hash:
bda0c0847b
)Short description of error
I noticed that Mantaflow does not bake the liquid particles with plane shaped flow object.
I also tested this on a beta version I downloaded back in 2020-01-21, and it works in the beta with planes, I wonder why that's the case.
(This is edited, so that the solidify modifier is removed. And I still believe it is valid since the beta did work, even with 64 resolution divisions.)
Exact steps for others to reproduce the error

Given how stretch your inflow object is, you simply need to increase the

parameter... No bug here.This comment was removed by @Eary
Ok, got it.
But still, delete the solidify modifier, and the beta version works, but not the stable version, I wonder why.

And I don't want this problem to be left not resolved because of my wording problem. Please compare the results from both the stable version, and the beta version from 2020-01-21 attached.

@sebbas think that one is for you to check then?
@Eary I just committed a fix (
cda81d5a4d
) that makes it easier to setup plane objects as emitters (same applies to planar obstacles). Now the only requirement is to set "Is Planar" in the flow objects. The object will have some thickness by default.Can you confirm that this fixes your issue?

Closing since, in my view, this is no longer an issue.
