Solution Techniques

CAEFEM supports the following types of methods for solution of equations. Depending on the requirement, user can easily select the solution method.

Direct method (Skyline)

	Robust method. Good for all types of analyses.
	Very efficient for multi load case analyses.

Direct Method (Sparse Solver from CA&SI)

	Robust method based on LU Decomposition
	Requires only a fraction of disk space and CPU time as compared to the Skyline solver. Hence very large frequency and nonlinear analyses can be performed using a PC with limited resources.

Iterative Method

Preconditioned Conjugate Gradient method (PCGLSS from CA&SI)

	User can select the convergence tolerance.
	Out of core solution scheme is also available.

Supports all elements.

Good for solution of very large sparse matrices.

Solution speeds up to Sixty times the speeds of direct methods have been observed.

Requires a fraction of disk space as compared to the direct methods.

Supports all analyses.
