"Large Problem Direct Sparse

A direct solver is available that leverages multicore processing capability and improves

solution speed for static and nonlinear studies.

In the Static or Nonlinear dialog box, under Solver, select Large Problem Direct Sparse.

By leveraging enhanced memory-allocation algorithms, the solver can handle simulation

problems that exceed the physical memory of your computer.

If you initially select the Direct Sparse solver and due to limited memory resources it

has reached an out-of-core solution, a warning message alerts you to switch to the Large

Problem Direct Sparse."

seems like the best of the best solver to choose?

also, is it chosen as part of the automatic solver option? when would it be chosen?
