Detailed Description

The NodeDescriptor class holds the information that the FEI implementation needs to know about the nodes in the finite element problem:

Global node identifier number of nodal degrees-of-freedom list of associated field identifiers, with their (global) equation numbers (global) blk-eqn number which processor is this node's owner list of (local) blocks that contain this node

Note: 'block' is used in two contexts here. There are element-blocks, and there are block-equations. Element-blocks refer to the blocks of elements in the finite-element problem, with all elements in a block containing the same number of solution fields per node, etc. Block-equations refer to the small dense sub-blocks of a block-entry sparse matrix. Each node is associated with a number of element-blocks, and each node has exactly one associated global 0-based block-equation number.

bool NodeDescriptor::getFieldEqnNumber ( int  fieldID,
int &  eqnNumber 
) const

Given a fieldID, return the first equation number associated with that field at this node.

Parameters:
fieldID 
eqnNumber 
Returns:
false if fieldID is not present at this node
