Transfers the data to the coarse level.

Restricts the residual to the right hand side of the coarse level system and initialies the left hand side of the coarse level system. These can afterwards be accessed usinf getCoarseLevelRhs() and getCoarseLevelLhs().

Parameters

fineDefect The current residual of the fine level system.

inlinevirtual

Updates the fine level linear system after the correction of the coarse levels system.

After returning from this function the coarse level correction will have been added to fine level system.

Parameters
