Relationship between number of nodes and the number of equations solve
- Thread starter jwshelt

and the number of equations solved (e) for a structural FEA problem?jwshelt,
It will depend on the number of degrees of freedom (DOF) for each node and the element connectivity (how the nodes are shared among adjacent elements. A good thread to look at for references on FEM/FEM basics is: thread727-22036. Best regards,

yes, i agree with MLoew. The number of equations solved (e) for a structural FEA problem is equal to the size of Stiffness matrix, a square matrix, where is it's size depend on the number of DOFs. Normally the number of DOFs is the sum of Nodes multiplied by DOFs at each nodes.
