The following methods are used to specify geometric parameters of the targets when these parameters are given by discrete FE functions. Note that every GridFunction given to the Set methods must use a H1_FECollection of the same order. The number of components must correspond to the type of geometric parameter and dimension.

Parameters

[in] tspec_ Input values of a geometric parameter. Note that the methods in this class support only functions that use H1_FECollection collection of the same order.
