Detailed Description

Class implementing cross section model in finite element problem. A cross section properties are not a constant values, but they can be set as scalar functions of the spatial position in terms of x,y,z variables. example "0.1+x*0.2+y*0.0", where (x,y,z) are global (or optionally local element) coordinates. This cross section model is a integral model, so it does not perform any integration over cross-section volume.

Note: varible cross section model uses the same keywords as simple cs model. As it is derived from simple cross section class, the initializeFrom method does not calls the parent method, because the same keywords are used to read variables of different type.

◆ give() [1/2]

double oofem::VariableCrossSection::give	(	CrossSectionProperty	a,
		const FloatArray &	coords,
		Element *	elem,
		bool	local ) const

overridevirtual

Returns the value of cross section property at given point (belonging to given element). the point coordinates can be specified using its local element coordinates or global coordinates (one of these two can be set to NULL) The default implementation assumes constant properties stored in propertyDictionary.

Parameters

a	Id of requested property.
coords	local or global coordinates (determined by local parameter) of point of interest
elem	reference to underlying element containing given point
gp	Integration point

Returns: Property value.
