Detailed Description

Abstract base class representing integration rule. The integration rule is a collection of integration points used to numerically integrate some formula. The number of integration points and their coordinates and integration weights depends on integration rule type (rule for integration in 1d, 2d, 3d) and required accuracy. General services for initialization are declared. Services for integration point retrieval are provided.

In general, finite elements can have multiple integration rules, for different tasks or when some components are integrated using reduced or selective integration. Therefore, first and last index variables are introduced to characterize components for which given integration rule applies.

The integration rule is a rather passive object. It does not perform numerical integration - it just provide way how to set up correct integration points and weights.

Because integration points contain related history parameters (using material status), the unique copy of integration rule must exist on each element. The integration rule is exclusively possessed by particular finite element.

Tasks:

• instanciating yourself
• returning number of integration points used
• returning requested integration point - method getIntegrationPoint
• returning interval of components (i.e.of local strain vector), where apply
• returning array of gauss points, according to specific integration rule (Gauss rule, Newton-Cotes rule, ...). integration points and corresponding weights are stored in Gauss point class.
• printing yourself
• updating yourself
• initializing for new time step
• saving & restoring context
