IPARS Multiblock Source Code

1. Multiblock code in IPARSv2 exists mainly in the "mortar" flavor.
2. Calls to mortar-specific routines are associated with
   keyword $MORTAR.
   $MORTAR CALL MORTAR_STEP(NERR)
3. The currently used framework "mortar" code is based on MACE (Multiblock Adaptive Computational Engine).
   MACE library: IPARSv2/MACE
4. IPARS-specific multiblock framework code is in
   MACE/utilities/mblk_mace/
5. Model dependent code for mortar multiblock is in model directories. Example: see object list in hydroi.mak
   MBOBJ = hm_util$(O) hfault$(O) hm_pc$(O) hm_vars$(O)
   • hm_util, hfault: initialization and setup of mortar boundary conditions
   • hm_vars: different choices of primary unknowns on the interface
   • hm_pc: implementation of mortar interface preconditioner
