Generating a surface mesh for use with lbm.write_mesh_to_vtk

[mckirkus]

I've stumped all LLMs so I thought I'd try here. I'm trying to export the surface of a fluid dynamics simulation using SURFACE cells and write_mesh_to_vtk. As I understand it, I need to use some sort of cube marching function to grab the TYPE_I cells and generate a mesh, which I understand the write_mesh_to_vtk function will write to disk.

It's not clear if I should write a series of meshes to disk, or extract the meshes from the exported VTKs using ParaView. Any ideas? Thanks!
