How to convert the .obj files to .bgeo files?

[ZF-Guo]

Hi,
I can get the model in .obj file format through 3D drawing software（UG, PRO/E ）, but this model can only be analyzed as a rigid body. So, I would like to consult how to get a .bgeo file with particle information?
I found that after importing graphics drawn in mm units, the units became inches.

Best wishes,

HI,

you can also use an OBJ file as FluidModel:

"FluidModels": [
{
"particleFile": "../models/bunny.obj",
"scale": [1, 1, 1]
}
]

Then the geometry is sampled with particles. However, the geometry must be closed and manifold.
Alternatively, you can use the tool VolumeSampling which is a part of SPlisHSPlasH.

Hope that helps!

Thank you very much for your reply.

Concerning units: The unit for distances are meters.
