Member Function Documentation

gsBoundaryConditions<T>& boundaryConditions ( )

inlineinherited

Returns a reference to the Pde boundary conditions.

There is also a const version returning a const reference.

gsMultiPatch<T>& domain ( )

inlineinherited

Returns a reference to the Pde domain.

There is also a const version returning a const reference.

GISMO_DEPRECATED int fieldDim ( index_t  field_id = 0 )

inlineinherited

gives the dimension of the i-th field it returns 1 for scalar fields, 2 for 2d vectors field etc.

Parameters

field_id

the field index

virtual gsPde<T>* restrictToPatch ( unsigned  ) const

inlinevirtual

restrictToPatch creats a new PDE object for a single patch np.

Parameters

np	the patch index

Returns

a pointer to an allocated gsPDE<T> object.
