FeenoX - v1.0 (Mar 2024)

• option --check
• README for engineers, hackers and academics
• thermal tutorial
• thermal radiation tests
• two-dimensional quasi-random number sequences
• non-zero Neumann BCs in neutron diffusion
• LABEL in now an alias for PHYSICAL_GROUP in MATERIAL
• explicit fission spectrum
• EIGEN_DIRICHLET_ZERO keyword
• special variable mumps_ictnl_14 to control MUMPS' over-relaxation factor
• improved MPI execution
• verification with MMS
• PRINTF and PRINTF_ALL instructions
• improved memory handling when building elemental objects
• PREALLOCATE and ALLOW_NEW_NONZEROS options
• choose either to fail or allow missed BCs
• updated internal naming of FEM matrices to match the doc
• dump element drawings, node ordering and shape functions with --elements_info
• cleaned up source distributions
• CI using Github actions
• Los Alamos criticallity benchmarks in tests
• support for reading VTK v5 files
• WRITE_RESULTS keyword
• split examples by problem type
• YAML blocks in input file for metadata are allowed (so far they are ignored by FeenoX)
• $0 (or ${0} or $(1)) expands to the base name of the main input, i.e. without the .fee extension
• bracketed argumens so ${1}1$(1) is a valid string
• multi-group neutron transport with discrete ordinates ($S_N$ method)
• mimicked-nodes BCs
• read mesh fields from VTK files

FeenoX - v0.3

• unofficial Debian/Ubuntu packages
• added jacobian for temperature-dependent conductivity
• updated LE10 benchmark
• read time-dependent functions in .msh files
• detect/handle hanging nodes
• muti-dof BCs using expressions for mechanical 0=expression of space & displacements
• volumetric forces in mechanical
• stress linearization according to ASME VIII Div 2 Sec 5.
• tangential and radial symmetry as multi-dof BCs using the penalty method
• solve (small) systems of non-linear equations given as expressions
• functions over meshes using vectors
• argument --pdes lists the available PDEs FeenoX can solve
• auto-detect PDE directories: if one adds or deletes one directory from src/pdes FeenoX will compile anyway.
• faster direct inversion of 3x3 matrices using code from PETSc
• separated initial conditions from initial guess
