New features

• 2nd order standalone FV solver
• Modal DG solver
• multi-block support
• Cartesian interpolator + FFT
• Point sampler
• Parallel serializer of Array<>: HDF5 now usable, but different partition not inter-operable
• Array / Solution / Mesh partition merger / remapping
• Multilevel assert / exception
• Reordering local cells
• Write mesh with CGNS (parallel): need 4.5.0

Optimization

• Better OMP utilization: most places OMPed
• OMP implementation in direct methods (Failed, consider using libraries or sub-partitions)
• Sub-partition for direct methods in OMP
• Direct methods’ code structure
• Comm-Comp Overlapping

Structure improvements

• Temporary TDof TRec allocator
• RunImplicitEuler modularize: in proceeding
• Packed long argument list

Build System

• CMake distinguishes EulerModel’s
• CCache acceleration
• CMake use external project to organize cfd_external? Using git submodule

Development

• Documentation
• Replace CGAL with MIT-compatible?
• Replace METIS with SCOTCH

Experimental

• Consecutive 2nd order - to - high order
• Implicit residual smoothing
• New overset
• Exponential Time Marching
• FV P-Multigrid
