Hi,
I have recently started using Griddle for meshing. And I found that the mesh I generate have a bad planarity of zone faces compared to other generation methods (which makes sens in a way as Griddle is used to handle more complex geometries).
Overall the meshes I generate are of good quality based on the Griddle log file, but when checking them in FLAC3D if find that have a large portion of the zones with planarity above 0.1. This confuses me because this planarity criterion does not seem to align with the shape quality criterion that Griddle uses.
Therefore, I have te following questions:
- Is there a way to constraint the planarity of zones in GVol? Based on my reading of the documentation of Griddle 3.0 it does not seem to be the case as the shape quality criterion used by Griddle seems to use a slightly different way of computing warping of faces.
- How does the Griddle criterions align with the flac3D criterions.
- How bad is a planarity between 0.1 and 0.3? The FLAC3D documentation is fairly sparse about it. It only says planarity should be << 1.
- Are there papers covering this topics? I could only find this 2013 paper (11-02.pdf) and it limited to investigating orthogonality and aspect ratio.
Thank you in advance!
