ogs: 6.0.4

Release notes 6.0.4 Features:

• Parallel computing framework for FEM by using PETSc, which also includes
  • Parallel input of partitioned mesh data.
  • Parallel output of solutions by using pvtu data format.
• New data structures for mesh properties are used everywhere replacing Element's value member.
• The penalty method to impose first-type boundary conditions was substituted with a non-penalty method for LIS and Eigen linear solvers.
• Support for multiple nodal variables is extended to the boundary conditions, the sparsity pattern.
• Passing of linear solver options from the project files is now possible.
• The global matrix and global vector type of indices is consistent with the linear solver library being used.

• Added CMake option OGS_CPU_ARCHITECTURE, #858, downloadable binaries build by Jenkins should now run on more CPUs
• Added CMake options for Boost, VTK and Eigen (OGS_LIB_BOOST, ...) to specify if libs are searched on the system first, then build them locally (Default), or you can specify to just use system libs (System) or force a local build (Local)
• Added CMake options for enabling Clang sanitizer:
  • OGS_ADDRESS_SANITIZER
  • OGS_UNDEFINED_BEHAVIOR_SANITIZER
• The zlib library is removed from ThirdParty directory.
• A LIS solver interface using Eigen's sparse matrices is now available through CMake option OGS_USE_EIGENLIS.
• CMake configuration uses ccache if available.

• Added offline viewable Doxygen documentation

• Fix all ogs-internal warnings on all OS.
• Move eigen solver compute call to solve(); different fix for 0237275
