Description DYNAFLOW is a finite element analysis program for the static and transient response of linear and nonlinear two- and three-dimensional systems. In particular, it offers transient analysis capabilities for both parabolic and hyperbolic initial value problems in solid, structural and fluid mechanics. There are no restrictions on the number of elements, the number of load cases, the number of load-time functions, and the number or bandwidth of the equations. Despite large system capacity, no loss of efficiency is encountered in solving small problems. In both static and transient analyses, an implicit-explicit predictor-(multi) corrector scheme is used. The nonlinear implicit solution algorithms available include: successive substitutions, Newton-Raphson, modified Newton and quasi-Newton (BFGS and Broyden updates) iterations, with selective line search options. Features include: Multi-field/physics analysis capabilities via selective specification of multiple solution staggers; Multi-staggered solution analysis options; Vectorized coding designed to fully exploit the architecture of vector and/or parallel machines; Coupled field equation capabilities for treatment of thermosolids, saturated porous media, multi-phase flows, and piezoelectric solids; Arbitrary Euler-Lagrange description options for fluid and/or fluid-structure(-soil) interaction problems; Generalized convective, radiative and enclosure radiative boundary condition options for heat transfer analysis; Prescribed nodal and/or surface forces options; Prescribed nodal displacement, velocity or acceleration options; Prescribed arbitrary load-time functions; Earthquake acceleration time history generation capability, for earthquake motions compatible with prescribed acceleration response spectra; Prescribed consistent free-field motion capability; Wave transmitting boundaries; Isoparametric data generation schemes (Cartesian, Cylindrical/Polar and Spherical); Element birth/death options to model addition (birth) or removal (death) of elements (material) in the physical system; Layout optimization analysis capabilities; Capability to perform constitutive experiments along prescribed stress and/or strain paths on selected material elements within the finite element mesh; Complete restart capabilities with options to selectively change input data; Graphics post-processing capabilities including mesh plots (2D/3D) displacement/ velocity vector plots, contour plots of selected nodal/field quantities, flownets, time history line plots of selected nodal/field quantities. Fully interactive colour postprocessors (2D/3D), with animation options; Fully integrated interface with the graphical pre- and post-processing program FEMGV; Free input format mode organized into data blocks by means of corresponding macro commands. The element library contains a one-dimensional, two-dimensional, and three-dimensional continuum element with axisymmetric options. An interface element with Coulomb friction, a contact element, a slide-line element with either perfect friction or frictionless conditions, a slide-line element with Coulomb friction, a truss element, a beam element, a plate/shell element, a membrane element, a boundary element and a link element are also available for two- and three-dimensional analysis. The material library contains a linear isotropic elastic model, a linear orthotropic elastic model, a nonlinear hyperelastic model, a nonlinear Von Mises viscoelastic model, a diffusive transport model, a linear/nonlinear thermal model, a linear/nonlinear heat conduction model, a linear piezoelectric model, a Newtonian fluid model, a Von Mises elasto(-visco)-plastic model, a Drucker-Prager elasto(-visco)-plastic model, a Mohr-Coulomb (Matsuoka's) elasto(-visco)-plastic model, an elasto-plastic Cap model, a multi-mechanism (Ishihara's) elasto-plastic model, and a family of multi-yield elasto(-visco)-plastic models.
