questions about the mantaflow version

[jiayaozhang]

Hi, this is really a interesting demo!

I have tried to fixed some bugs before I can compile the TUM.py and Plume.py run.

From
OBSTACLE_MASK = HardGeometryMask(OBSTACLE.geometry) >> CenteredGrid(0, extrapolation.BOUNDARY, **DOMAIN)
to

OBSTACLE_MASK = CenteredGrid(HardGeometryMask(OBSTACLE.geometry), extrapolation.BOUNDARY, **DOMAIN)

From
buoyancy_force = smoke * (0.1, 0, 0) >> velocity
to
buoyancy_force = smoke * (0.1, 0, 0) @ velocity

But there are still some errors that I can not fixed, can you help with it?

I am trying to figure out which manta version it is needed.

first manta

/home/janice/Documents/mantaPatch/build/manta manta2vdb.py -d /home/janice/Documents/phiflow2blender/tutorial/data/Plume/ -res 32 32 32

second manta

/home/janice/Documents/den2vel/mantaflow/build/manta manta2vdb.py -d /home/janice/Documents/phiflow2blender/tutorial/data/Plume/ -res 32 32 32

third manta

/home/janice/Documents/phiflow2blender/manta/build/manta manta2vdb.py -d /home/janice/Documents/phiflow2blender/tutorial/data/Plume/ -res 32 32 32

fourth manta

/home/janice/Documents/tum_nil/mantaflow/build/manta manta2vdb.py -d /home/janice/Documents/phiflow2blender/tutorial/data/Plume/ -res 32 32 32

And get the corresponding errors

So I am wondering which manta version you are referring to?
Thanks !

Hey @jiayaozhang thanks a lot for your message and for your kind words! Also thanks for the fixes, can you open a PR with them? At the time that I wrote the tutorial it was still the early days of phiflow v2, so maybe the API had some changes since then.

Regarding your issue, I just used the latest manta version (which hasn't changed for some years now I think). When building mantaflow, did you enable the OPENVDB option in CMAKE?

It seems that I forgot to add this in the tutorial instructions... let me know if this solves your problem so that I can add it, and if not I'll try to look further into it:)

Yes, firstly I add openvdb in my cmake

Then make -j 32, compile successfully

Finally, I add from manta import * into mata2vdb.py file

However I got this error
