Detailed Description

Base class for all Elements.

This is the base class for all elements used in KRATOS Elements inherited from this class have to reimplement all public functions that are needed to perform their designated tasks. Due to a dummy implementation of every function though, not all of them have to be implemented if they are not needed for the actual problem

Access for variables on Integration points. This gives access to variables stored in the constitutive law on each integration point. Specializations of element must specify the actual interface to the integration points! Note, that these functions expect a std::vector of values for the specified variable type that contains a value for each integration point! SetValuesOnIntegrationPoints: set the values for given Variable. CalculateOnIntegrationPoints: get/calculate the values for given Variable. these methods are: OPTIONAL
