Ansys Mechanical

Ansys Mechanical enables you to solve complex structural engineering problems and make better, faster design decisions. With the finite element analysis (FEA) solvers available in the suite, you can customize and automate solutions for your structural mechanics problems and parameterize them to analyze multiple design scenarios. Ansys Mechanical is a **
dynamic tool that has a complete range of analysis tools.

Ansys Parametric Design Language (APDL)

Ansys Parametric Design Language (APDL) is a powerful structured scripting language used to interact with the Ansys Mechanical solver. Mechanical APDL (MAPDL), a finite element analysis program, is driven by APDL. APDL and MAPDL can be used for many tasks, ranging from creating geometries for analysis to setting up sophisticated solver settings for highly complex analyses. Ansys was the first commercial simulation tool provider to offer users a versatile programming language to create parametric models for systemic analyses.

Ansys LS-DYNA

Ansys LS-DYNA is the most used explicit simulation program in the world and is capable of simulating the response of materials to short periods of severe loading. Its many elements, contact formulations, material models and other controls can be used to simulate complex models with control over all the details of the problem.
