Classes
struct	Ikarus::ResultWrapper< RT, storedResultShape >
	Container that is used for FE Results. It gives access to the stored value, but can also be used to access the result in Matrix and Vector form. More...
struct	Ikarus::ResultTypeBase< ResultTypes >
	Base class for element definitions that provides common functionality for ResultTypes. More...

Namespaces
namespace	Ikarus

#define	REGISTER_SIMPLE_SYMMETRIC_RESULTTYPE(resultTypeName, rowsExpr, colsExpr, strainlike)
	Used to register a symmetric ResultType with compile-time fixed rows and columns (uses Voigt notation) More...
#define	REGISTER_RESULTTYPE(resultTypeName, rowsExpr, colsExpr)
	Used to register a general ResultType with potentially dynamic size without reserved memeroy rows and columns. More...
#define	REGISTER_RESERVED_RESULTTYPE(resultTypeName, rowsExpr, colsExpr, MaxRowsExpr, MaxColsExpr)
	Used to register a general ResultType with potentially dynamic size and defined maximum amount of rows and columns. More...
#define	REGISTER_SIMPLE_RESULTTYPE(resultTypeName, rowsExpr, colsExpr)    REGISTER_RESERVED_RESULTTYPE(resultTypeName, rowsExpr, colsExpr, rowsExpr, colsExpr)
	Used to register a general ResultType with potentially dynamic size, with reserved memory according to passed in rowsExpr and colsExpr. More...
