If we want, we can export our simulation to Alembic. This can be useful if we need to use our geometry outside of blender or in another file.
Note that when exporting to Alembic, the Velocity attribute is not exported, so you will not be able to have MotionBlur in the fluid.
We will be able to configure the export so that once it finishes, it auto imports the Alembic and hides the particle simulation and the Mesh generated in GN, to work only with the Alembic.
We can also export a single frame to OBJ, in case we want to use that mesh/fluid as Collider.
