Detailed Description

template<typename Trafo_, typename SurfaceShape_>
class FEAT::Assembly::SurfaceIntegrator< Trafo_, SurfaceShape_ >

Assemble class Discrete Integrale of an FE function over a d-1 manifold.

Template Parameters

Trafo_	The trafo on which the FE spaces are defined on
SurfaceShape_	The shapetype of the surface elements

Note: For now, this only works for piecewise defined triangulations and we assume no cuvature on the single segments. Maybe we will add this in the future.

Also any vertex mapping provided to this class is assumed to have the 0-th submanifold ordering in the sense of the FEAT3 mesh element mapping, i.e. We always look onto the inner face and the ordering is always left to right:

Line2d: 0 --— 1

Quad: 2 --— 3 | | | | 0 --— 1

Triang: 2 | - | | | - 0 — 1

Note: It is assumed, that the normal orientation is the same for all elements. We generally assume we view from the outside, so you have to set the _view_inside variable if this is not case.

Sets the cell mask vector, which sorts out any cells completelly outside the fluid domain.

Parameters

[in] cell_mask_vec Mask vector, for example generated by fbm_asm->get_fbm_mask_vector(dim)

Note: the mask vec has to match the size of all entities of the background mesh and holds the following encoding 3 -> cell is complettly inside the fbm region, thus the cell is ignored any other -> cell has some subdimensional entitiy, which is outside the fbm region, i.e. part of the fluid domain
