Nektar::Collections::PhysDeriv_Helper Class Reference

Physical Derivative help class to calculate the size of the collection that is given as an input and as an output to the PhysDeriv Operator. The Operator evaluation is happenning in the physical space and the output is expected to be part of the physical space too. More...

Detailed Description

Physical Derivative help class to calculate the size of the collection that is given as an input and as an output to the PhysDeriv Operator. The Operator evaluation is happenning in the physical space and the output is expected to be part of the physical space too.
