PHiLiP Version 2.0.1

Fixing release title on Zenodo.

PHiLiP Version 2.0.0

Since last release, many features have been developed and many collaborators have joined the project.

Among others:

• Compatibility with ROL for optimization purposes
• Full-space unconstrained optimization of an inverse design problem
• Anisotropic grid refinement through Gmsh
• Subscell shock capturing
• Freeform deformation as an optimization parametrization
• BR2 numerical flux for diffusion differential equations
• Low dissipation Roe flux for Euler-type convective flows
• Navier-Stokes equations!
• Physical and enthalpy-preserving artificial dissipation
• Reduced-Order Modelling using POD-Galerkin
• POD basis optimization
• ODESolver class restructuring
• FlowSolver class that will significantly reduce testing development time
• h-refinement validation
• Dual-weighted residual (adjoint-based or goal-oriented) error indicator for mesh refinement
• No-slip BC allowing us to solve for Naver-Stokes equations on external aerodynamic problems
• and many more improvements and bug fixes

Thank you to all the new contributors.

PHiLiP Version 1.0.0

Currently supports
