VfsTools
The VfsTools
library from Visual Kinematics, Inc.
is an object-based software development toolkit designed to enable
the solution of the systems of equations which typically occur in finite
element simulations.
VfsTools enables programmers to manage global system degrees of freedom,
assemble and solve linear systems and compute eigenvalues and eigenvectors
for large linear systems.
Features
-
Global degree of freedom management.
-
Matrix assembly in sparse Harwell-Boeing, full or diagonal formats.
-
Direct and iterative solution of large linear systems of equations.
Solution techniques include direct sparse solvers and preconditioned
conjugate gradient iterative solvers.
-
Compute the generalized eigenvalue problem for large linear systems.
This enables the user to compute buckling loads and normal modes of
vibration.
-
Perform static matrix condensation for large systems.
-
Perform general Ritz reductions of system matrices.
-
Object-based architecture, written in ANSI C with C++ and FORTRAN
language bindings.
-
Hardware and O/S independence.
