What is PANDAS?
PANDAS is a FE solver for continuum-mechanical problems.
PANDAS has been designed in the early 90th of the last century and has been continuously developed since then.
PANDAS is a solver for volumetrically coupled multi-field problems.
The basis version of PANDAS can be used as a stand-alone tool.
PANDAS versions are available that can be coupled to commercial and open-source solvers,
such that FE formulations and material models defined in PANDAS can be used in foreign solvers.
Actually, PANDAS can be coupled to Abaqus (implicit und explicit), LS-DYNA (implicit und explicit) and DUNE.
PANDAS and its includable material properties:
Solids (porous and non-porous): infinitesimal and finite deformations,
elastic, plastic und viscous properties (combinable), consideration of temperature variations.
Pore fluids (liquids and/or gases): compressible and incompressible material behaviour, viscous and non-viscous
material properties, temperature variations, phase transformations, integration of fluid mixtures.
