Change log

1.3 (2020-08-18)

• Add option to use Garlerkign Least Squares (GLS) stabilization
• Allow for different chi_tilde on boundaries

• Add option for multiple mesh regions:

  • Allows for different Knudsen numbers in regions
  • Add new example: Lid-driven cavity with two mesh regions

• Optimization of CI pipeline and scripts in Gitlab:

  • Assert Flake8 compliance

• Add option to output solution vectors (for model order reduction experiments)
• Improve README with R13 equation set and list of features

1.2 (2020-02-17)

• Change system:

  • Change RHS for energy coupling consistency
  • Add delta term
  • Add body force
  • Add div(u) coupling to energy balance (also change RHS for elimination)
  • Rename deltas and chi_tilde

• Add body froce driven channel flow
• Add P2P1P1P2P1 R13 validation case
• Revert to MUMPS solver

1.1 (2019-12-15)

• Symmetrize system

  • Scale the equations to match
  • Introduce subfunctionals
  • Subfunctionals are equal for off-diagonal entries
  • Resolve stf-terms using orthogonality
  • Make r13 as default in formulation rather than decoupled
  • Refactor CIP as separate subfunctionals
  • Add antisymm ring, not used for now but can improve convergence

• Create package

  • Move files into separate folder and add setup.py
  • CI is changed
  • Installation through "pip install ." in toplevel

• Clean repository

1.0 (2019-09-23)

• Improve examples

  • Remove auxiliary files, clean cases, improve output plots and change some meshes

• Add WELCOME screen to Docker container with link to website and documentation
• Introduce more variables as dolfin.Constant() for parameters study w.o. compiling
• Add time measure for linear solve
• Thesis submission version

0.5 (2019-09-13)

• Add more examples with tests and documentation:

  • Lid-Driven Cavity
  • Channel Flow with Knudsen paradox plot
  • Knudsen pump

• Add option to perform parameter studies
• Add massflow reporting option for arbitrary BCs
• Fix P1P2P4 stress test case
• Add more printing statement to program output

• Change formulation:

  • Rename gamma to epsilon in inflow model
  • Rename tau to Knudsen to have real dimensionless equations
  • Replace sym(psi) -> psi because symmetric per definition
  • Fix stf3d2 for arbitrary

• Extend documentation:

  • Extended tutorial
  • Move legacy notes to bottom of README

0.4 (2019-08-21)

• Finish documentation

  • Also includes some doctests to test for edge cases

• Introduce develop branch to only have major version at master branch
• Add relative error calculation
• Add channel flow example (to test for Knudsen paradox)

• Fix error calculation for higher-order Ansatz function

  • The previous error was based on DOFS (P2 elements therefore differ), the new error is based on vertex values

0.3 (2019-08-11)

• Full linear R13 now converges
• Inflow model works
• Restructuration of BC specification
• Minor improvements in plotting routine

0.2 (2019-07-29)

• Decoupled stress system converges

• Add separated tensor operations module

  • This was needed to implement operations on synthetic 3D tensors

• Add pytests for stress
• Add new logo
• Add more Sphinx documentation
• Restructure repository

0.1 (2019-07-17)

• Add logo
• Add Sphinx documentation
• Add pytests
• Add Gitlab CI scripts
