VfeTools
The VfeTools
library from Visual Kinematics, Inc.
is an object-based software development toolkit designed for
generating finite element component matrices and vectors that add
functionality
to new or existing general purpose finite element programs, flexible body
simulations, or special purpose analysis tools tailored for a particular
application.
VfeTools enables programmers to compute standard quantities arising from
the finite element method such as stiffness and
mass matrices, consistent load vectors, stress and strain, etc.,
that are generated at the element level.
Designed to provide robust and efficient element formulations in a modular,
object-based architecture,
VfeTools imposes few restrictions on the
specific data structures used within a host application to maintain the
computational grid and/or solution results.
Features
-
Support for solid and structural elements in both 2D and 3D.
-
2D elements support plane strain, plane stress and axisymmetry.
-
All elements include large strain, large deformation
nonlinear capability.
-
All shell and beam element formulations are
geometrically exact and implemented to be singularity free for
any degree of rotation.
-
Generation of stiffness, consistent or diagonal mass and geometric
stiffness matrices for structural analysis.
-
Generation of conductance and consistent and diagonal capacitance
matrices for thermal analysis.
-
Generation of consistent nodal force vectors for edge and/or face
loading.
-
Robust element technologies that avoid
locking mechanisms and/or rank deficiencies in both the infinitesimal
and large deformation regimes.
-
Methods for easy integration into new or existing finite element
applications.
-
Support for computation for either one or multiple elements at a
time (so called blocking), with significant performance increases
realized using blocked format.
-
Element properties include variable thickness and laminated shells,
tapered and general cross section beams.
-
Element independent corotational utilities for implementing large
rotation capabilities.
-
Abstract interface between elements and material models allowing
users to add their own material models.
-
Linear material models include isotropic, orthotropic and
anisotropic materials.
-
Nonlinear material models include large strain plasticity,
hyperelasticity and viscoelasticity.
-
All material models are temperature dependent
-
Disciplines include structural and thermal analysis.
-
Hardware and operating system independence.
