Ambit – A FEniCS-based cardiovascular multi-physics solver - Ambit v1.2.9

• Make code compatible with latest dolfinx release and development version
• Still keep option to use old mixed dolfinx branch, since all functionality of it has not yet been fully transferred
• Option for spatial expression in Robin valve viscosity
• Minor fixes

Ambit – A FEniCS-based cardiovascular multi-physics solver - Ambit v1.2.5

Fixes: - Simultaneous time-controlled Dirichlet and Neumann conditions using old state (e.g. for mid-point time scheme) were wrong due to false access of old time curve values - Periodic reference state estimation of solid-flow0d problem - Restart of Frank-Starling models - FrSI prestressing - Several other minor fixes

Features: - Allow user to pass PETSc options to preconditioner - Support for latest dolfinx (not yet for mixed branch, e.g. FSI or valves/immersed fluid surfaces) - Spatial expressions in Neumann loads - Crossfiber active stress models
