DMCompositeSetCoupling#

Sets user provided routines that compute the coupling between the separate components DM in a DMCOMPOSITE to build the correct matrix nonzero structure.

Input Parameters#

  • dm - the composite object

  • FormCoupleLocations - routine to set the nonzero locations in the matrix
