Frontal solver

Frontal solution requires very intricate bookkeeping for tracking coefficients and making sure that all of the stiffness equations have been assembled and fully reduced. The process time requirement in frontal solvers is hence larger than a straightforward band solver for equal size problems. 

Another consequence of using this strategy is that, unlike band solver routines, global node numbering in frontal solvers may be done in a completely arbitrary manner. How ever, better computer economy is achieved if an element numbering which minimizes front width is used. In general, manipulation of...
