void FETriphasicDomain::SolidElementStiffness	(	FEM &	fem,
		FESolidElement &	el,
		matrix &	ke
	)		`[protected]`

calculates the solid element stiffness matrix for steady-state response

This function calculates the element stiffness matrix. It calls the material stiffness function, the geometrical stiffness function and, if necessary, the dilatational stiffness function. Note that these three functions only calculate the upper diagonal matrix due to the symmetry of the element stiffness matrix The last section of this function fills the rest of the element stiffness matrix.

void FETriphasicDomain::TriphasicMaterialStiffness	(	FEM &	fem,
		FESolidElement &	el,
		matrix &	ke
	)		`[protected]`

material stiffness component

Calculates element material stiffness element matrix.
