Member Function Documentation

getRule()

int TriFE::getRule ( int order_row, int order_col, int order_data )

virtual

another variant of getRule

Parameters

order_row	order of base function on row
order_col	order of base function on columns
order_data	order of base function approximating data

Returns

integration rule

This function is overloaded by the user. The integration rule is set such that specific operator implemented by the user is integrated accurately. For example if user implement bilinear operator

\[ b(u,v) = \int_\mathcal{T} \frac{\partial u_i}{\partial x_j}\frac{\partial v_i}{\partial x_j} \textrm{d}\mathcal{T} \]

then if \(u\) and \(v\) are polynomial of given order, then exact integral would be

 int getRule(int order) { return
2*(order-1); }; 

The integration points and weights are set appropriately for given entity type and integration rule from quad.c

Method ForcesAndSourcesCore::getRule takes at argument takes maximal polynomial order set on the element on all fields defined on the element. If a user likes to have more control, another variant of this function can be called which distinguishing between field orders on rows, columns and data, the i.e. first argument of a bilinear form, the second argument of bilinear form and field coefficients on the element.

Note

If user set rule to -1 or any other negative integer, then method ForcesAndSourcesCore::setGaussPts is called. In that method user can implement own (specific) integration method.

Bug

this function should be const

Reimplemented from MoFEM::ForcesAndSourcesCore.

Examples

prism_elements_from_surface.cpp.

Definition at line 464 of file prism_elements_from_surface.cpp.

{ return -1; }

setGaussPts()

MoFEMErrorCode TriFE::setGaussPts ( int order_row, int order_col, int order_data )

virtual

set user specific integration rule

This function allows for user defined integration rule. The key is to called matrix gaussPts, which is used by other MoFEM procedures. Matrix has number of rows equal to problem dimension plus one, where last index is used to store weight values. Number of columns is equal to number of integration points.

Note

This function is called if method ForcesAndSourcesCore::getRule is returning integer -1 or any other negative integer.

User sets

MatrixDouble gaussPts;

where

gaussPts.resize(dim+1,nb_gauss_pts);

number rows represents local coordinates of integration points in reference element, where last index in row is for integration weight.
