Best file format for volumes defined by surfaces


I am a new ParaView user. I have a file which i want to read. It is essentially a Finite Volume mesh. The mesh is written with a custom software and I would like to be able to visualize the mesh using ParaView. The problem i have is that the volumes used in the mesh are defined in a text file as such: xmin, ymin, zmin, xmax, ymax, zmax, attr1, attr2. From the xmin…zmax coordinates i can extract the corner points of the rectangles. I can also extract the connectivity after some tedious work and create a VTK file, but i was wondering if there is a more suitable file type that i could use, or a more efficient method to have ParaView read the volumes.

Thank you!

It depends on the type of mesh you are using. Have a look a the possible formats

If you are using a structured or rectilinear grid, the coordinates + some metadata should be sufficient . Non-regular topology would require to pass the connectivity also.
