◆ revertSqrt()
Reverts the square-root operation on some norm quantities.
- Parameters
-
gNorm Global norm values eNorm Element norm values
This method is used to fix the problem that all norm quantities (global and on element level) will be subjected to a final square-root operation after they have been integrated and accumulated, through NormBase::applyFinalOp(). However, a few quantities (like the volume and variationally consistent postprocessing values) should not reveive this operation.
