GitLab now enforces expiry dates on tokens that originally had no set expiration date. Those tokens were given an expiration date of one year later. Please review your personal access tokens, project access tokens, and group access tokens to ensure you are aware of upcoming expirations. Administrators of GitLab can find more information on how to identify and mitigate interruption in our documentation.

Merged FVM derivation: use a smaller stencil before trying brute-force to find the sparsest stencil

fvm-derivation into master

Merged Michael Kuron requested to merge fvm-derivation into master 5 years ago

D3Q7/D2Q5 should suffice for first derivatives, so try that stencil first before using brute force to find the sparsest D3Q27/D2Q9 stencil. In 2D, it does not really matter because the brute-force search is so fast, but in 3D it can take days to complete (due to that itertools.product). This pull request does not change the resulting stencil weights, it only massively speeds up the process of determining them.
