2.8 General Solving Procedure

The complete solving procedure for a time dependent problem has the following structure,

This yields values of for discrete times . Automatic time step and mesh control are discussed in the next section. As the terminating condition (condition( ) in the Solving Algorithm) for the Newton loop, the following inequalities are commonly used,
