Definitions

Data Description SI Unit Example
Type
MORGRO (Mortar method coarse)
The space of Lagrange multipliers correspond to the coarse mesh.
MORFIN (Mortar method fine):
The space of Lagrange multipliers correspond to the fine mesh.
HERRY (optimal method):
The space of Lagrange multipliers correspond to both coarse and fine mesh.
  

Comments

  1. The optimal method is used by default, as it is more accurate.
  2. Mortar methods could be used to reduce the number of Lagrange multipliers to be computed and then the CPU cost of RAD2RAD. But by using the Mortar methods, the continuity condition between domains is no longer exactly ensured.
