v22.0

What is new?

• Multi-session (uncoupled) support
• Support unaligned symmetry boundary condition
• Support (unaligned) traction boundary condition
• Better performance on AMD MI-GPUs
• FLOP counters
• Various bug fixes

Good to know

• OpenCL support is now disabled by default

Breaking Changes

• [udf] Rename udfBuildKernel => oudfBuildKernel
• [par] Separate details of coarse grid discretization from coarse grid solver
  e.g., coarseSolver = SEMFEM+AmgX is replaced by
  coarseSolver = AmgX and coarseGridDiscretization = SEMFEM
• [par] Remove preconditioner=semg and preconditioner=semg_amg
• [udf] Rename plug-in name avg => tavg
• [udf] Rename udf.converged => udf.timeStepConverged
• [nrsconfig] Rename env-var AMGX_ENABLE => ENABLE_AMGX

Known Bugs / Restrictions

• Mesh solver does not support CHT and unaligned sym/shl BCs
• 729
• 300
• 258
