Detailed Description

class for piecewise constant coefficient

Definition at line 82 of file coefficient.hpp.

Constructor & Destructor Documentation

mfem::PWConstCoefficient::PWConstCoefficient ( int NumOfSubD = 0 )

inlineexplicit

Constructs a piecewise constant coefficient in NumOfSubD subdomains.

Definition at line 90 of file coefficient.hpp.

mfem::PWConstCoefficient::PWConstCoefficient ( Vector & c )

inline

c should be a vector defined by attributes, so for region with attribute i c[i] is the coefficient in that region

Definition at line 95 of file coefficient.hpp.

double mfem::PWConstCoefficient::Eval	(	ElementTransformation &	T,
		const IntegrationPoint &	ip
	)

virtual

Evaluate the coefficient function.

Definition at line 24 of file coefficient.cpp.

int mfem::PWConstCoefficient::GetNConst ( )

inline

Returns the number of constants.

Definition at line 108 of file coefficient.hpp.

double& mfem::PWConstCoefficient::operator() ( int i )

inline

Member function to access or modify the value of the i-th constant.

Definition at line 102 of file coefficient.hpp.

void mfem::PWConstCoefficient::operator= ( double c )

inline

Set domain constants equal to the same constant c.

Definition at line 105 of file coefficient.hpp.

void mfem::PWConstCoefficient::UpdateConstants ( Vector & c )

inline

Update constants.

Definition at line 99 of file coefficient.hpp.
