Detailed Description
Caches precalculated shape function values.
PrecalcShapeset is a cache of precalculated shape function values.
Constructor & Destructor Documentation
| Hermes::Hermes2D::PrecalcShapeset::PrecalcShapeset | ( | Shapeset * | shapeset | ) |
Constructs a standard (master) precalculated shapeset class.
- Parameters
-
shapeset[in] Pointer to the shapeset to be precalculated.
Definition at line 24 of file precalc.cpp.
| Hermes::Hermes2D::PrecalcShapeset::PrecalcShapeset | ( | PrecalcShapeset * | master_pss | ) |
Constructs a slave precalculated shapeset class.
The slave instance does not hold any precalculated tables. Instead, it refers to those contained in the master instance. However, the slave can have different shape function active, different transform selected, etc. Slave pss's are used for test functions when calling bilinear forms, inside Solution so as not to disrupt user's pss, etc.
- Parameters
-
master_pss[in] Master precalculated shapeset pointer.
Definition at line 36 of file precalc.cpp.

Ensures subsequent calls to get_active_element() will be returning 'e'. Switches the class to the appropriate mode (triangle, quad).
Reimplemented from Hermes::Hermes2D::Transformable.

| void Hermes::Hermes2D::PrecalcShapeset::set_active_shape | ( | int | index | ) |
Activates a shape function given by its index. The values of the shape function can then be obtained by setting the required integration rule order by calling set_quad_order() and after that calling get_values(), get_dx_values(), etc.
- Parameters
-
index[in] Shape index.
