NSTACK
Linear solver stack size
The data represents the size of the stack of previous search directions held by the ORTHOMIN linear solver (see "Solution of the Linear Equations" on page 821 of the "ECLIPSE Technical Description"). This may be increased if the linear solver shows convergence problems. A good value for many ECLIPSE 100 problems is 10, while many compositional ECLIPSE 300 problems often require 40. Difficult problems may require a larger value. ECLIPSE prints a message advising increased NSTACK if this will increase computing efficiency. Increasing the value of NSTACK increases the memory required for a run.
