In the solution phase of an analysis, the computer takes over and solves the simultaneous set of equations that the finite element method generates. The results of the solution are:
Nodal degree of freedom values, which form the primary solution
Derived values, which form the element solution.
The element solution is usually calculated at the elements' integration points. The program writes the results to the database as well as to the results file (.rst, .rth, or .rmg files).
