Rework force models and central moments transform (!92) · Merge requests · pycodegen / lbmpy · GitLab

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.

Markus Holzer requested to merge holzer/lbmpy:ShiftMatrix into master Aug 09, 2021

This MR provides a complete rework of the force model, so they are functioning in the moment space and the central moment space.

Furthermore, a new implementation for the shift matrix is provided and a rework of the central moment based method.

The central moment transform classes are adapted to be able to work with the changes.

TODOs:

Test Fixed Density BC when method has a force model
Forward/Backward Transform for D3Q15
make cumulants aware of polynomials
rework cumulants with force
