Detailed Description

Fixture class for swept volume moments computation tests.

Here, we consider a 3D cartesian grid which is advected by a unique displacement vector and we aim to check the volume of each swept region for a given source cell. Notice that mesh topology remains unchanged, hence source and target cells and faces indices are kept.

Constructor & Destructor Documentation

IntersectSweptBase3D() [1/2]

IntersectSweptBase3D::IntersectSweptBase3D ( )

delete

Disabled default constructor.

IntersectSweptBase3D() [2/2]

IntersectSweptBase3D::IntersectSweptBase3D ( double  x0, double  y0, double  z0, double  x1, double  y1, double  z1  )

inline

Setup each test-case.

It initializes both source and target meshes and states, then computes and assigns a density field on source mesh.
