Introduced in 1996, ANSYS LS-DYNA capabilities have helped customers in numerous industries to resolve highly intricate design issues. ANSYS Mechanical users have been able take advantage of complex explicit solutions for a long time utilizing the traditional ANSYS Parametric Design Language (APDL) environment. These explicit capabilities are available to ANSYS Workbench users as well. The Workbench platform is a powerful, comprehensive, easy-to-use environment for engineering simulation. CAD import from all sources, geometry cleanup, automatic meshing, solution, parametric optimization, result visualization and comprehensive report generation are all available within a single fully interactive modern graphical user environment.
