PHLEXsolid
PHLEXsolid
is an hp-adaptive finite element based simulation tool designed
to optimize the solution process for three-dimensional solid continuum
mechanics problems.
PHLEXsolid
Technology
PHLEXsolid represents
the first of a new breed of computational mechanics modeling technology
which utilizes rigorous a-posteriori error estimation and fully unstructured,
anisotropic refinement and polynomial enrichment of the finite element
computational domain space. By optimizing the computational domain to systematically
reduce the discretization error, numerical results with a quantifiable
level of accuracy are attained with minimal numbers of degrees of freedom
and with minimum user intervention.
PHLEXsolid is built on an hp-adaptive finite
element kernel PHLEX. This kernel
provides a high level of modularity and modeling flexibility for creating
single and multi-physics customized applications for engineering design
and analysis.
Benefits
Using the PHLEXsolid
solution adaptive approach engineering problems can be solved much more
accurately than with conventional fixed-grid techniques. PHLEXSolid
improves
engineering productivity by removing the guesswork inherent with mesh generation.
Features
The current release of PHLEXsolid
focuses on modeling three-dimensional structures and geometrically complex
assemblages composed of elastic and/or hyperelastic materials. The equilibrium
equations may be modeled using small deformation or large deformation mechanics
for static or quasi-static loading conditions. The loading/boundary conditions
include pointwise and distributed constraints, point forces and distributed
tractions, pressure loads as well as follower pressures and contact with
composite rigid surfaces.
