Hi, I am trying to create a voxel-based mesh by reading TIFF files obtained from the CT scanning of the specimen. The geometry has a lot of pores, and of course, these elements should be removed from the triangulation object. I tried to create first a structured grid using subdivided hyper-rectangle and then removed the cells which corresponded to pores using the create_triangulation_with_removed_cells. I managed to do this for one single image by using parallel::distributed::triangulation. However, this strategy won't work when I try to read a lot of images and create a 3d mesh. Because in this case, the coarse mesh itself is quite large. And also reading from an externally created mesh file is taking forever in this case. I want to ask if there is a simple way to create a voxel-based mesh for the parallel::fullydistributed::triangulations and easily remove the cells which correspond to air?
