Automatic Solver
SelectionThe algorithm that selects the best
equation solver is improved to include Nonlinear, Frequency, and Buckling
studies. The selection of the best equation solver (Intel Direct Sparse or
FFEPlus Iterative) depends on the number of equations, load cases, mesh
type, geometric features, contact and connector features, and available
system memory.
For Frequency studies, in addition to
the previously mentioned parameters, the algorithm also factors in the
number of frequencies. For Buckling studies, it factors in the number of
modes.
