Solving Method
The following options are added to the Frame Analysis Settings Solver tab to provide robustness and stability.
Solver tab to provide robustness and stability.
- Automatic - Relies on a set of rules to select the appropriate method.
- Frontal - Uses the Gauss elimination method.
- Skyline - Uses the Cholesky LDLt factorization method.
- Sparse - Uses nested dissection method (NDM).
- Sparse M - Uses minimal degrees algorithm (MDA).
- Multi-threaded- Uses PARDISO solver from the Intel® Math Kernel Library.
