COMSOL Multiphysics® is a general-purpose platform software for modeling engineering applications. You can use the core package on its own or expand its functionality with any combination of add-on modules for simulating designs and processes based on electromagnetics, structural mechanics, acoustics, fluid flow, heat transfer, and chemical engineering behavior. The add-on modules and LiveLink™ products connect seamlessly via one integrated software environment. This means that your modeling workflow remains the same regardless of what you are modeling. You can combine as many expansion products as you need.

The Application Builder in COMSOL Multiphysics® makes it possible for simulation experts to create intuitive and dedicated user interfaces for their otherwise general computer models — ready-to-use custom apps. You can run apps using COMSOL Multiphysics® or COMSOL Server™, which is a product for deploying, managing, and running apps that were made with the Application Builder. Use this tool to make apps accessible to colleagues, partners, or customers worldwide.

Modern products are complex. A detailed understanding of how they perform is key to ensuring safe and reliable function. Fluid forces, thermal effects, structural integrity and electromagnetic radiation can all impact performance. If you isolate these forces and examine them separately, you may not get an accurate prediction of product behavior. ANSYS Multiphysics solutions can help you examine these effects in any combination, achieving the highest fidelity solution to eliminate reliability problems and design safe and effective products.

MOOSE (Multiphysics Object Oriented Simulation Environment) is an object-oriented C++ finite element framework for the development of tightly coupled multiphysics solvers from Idaho National Laboratory. MOOSE makes use of the PETSc non-linear solver package and libmesh to provide the finite element discretization.

MOOSE is a development and run-time environment for the solution of multi-physics systems that involve multiple physical models or multiple simultaneous physical phenomena. The systems are generally represented (modeled) as a system of fully coupled nonlinear partial differential equation systems (an example of a multi-physics system is the thermal feedback effect upon neutronics cross-sections where the cross-sections are a function of the heat transfer). Inside MOOSE, the Jacobian-Free Newton Krylov (JFNK) method is implemented as a parallel nonlinear solver that naturally supports effective coupling between physics equation systems (or Kernels). The physics Kernels are designed to contribute to the nonlinear residual, which is then minimized inside of MOOSE. MOOSE provides a comprehensive set of finite element support capabilities (libMesh) and provides for mesh adaptation and parallel execution. The framework heavily leverages software libraries from the Department of Energy (DOE) and the National Nuclear Security Administration (NNSA), such as the nonlinear solver capabilities in either the Portable, Extensible Toolkit for Scientific Computation (PETSc) project or the Trilinos project.

The engine is hidden entirely behind simple C++ classes, so that no OpenCL knowledge is required from application programmers. Mesh-free, immersed boundary approach allows one to move from CAD directly to simulation drastically reducing pre-processing efforts and amount of potential errors. ASL can be used to model various coupled physical and chemical phenomena and employed in a multitude of fields: computational fluid dynamics, virtual sensing, industrial process data validation and reconciliation, image-guided surgery, computer-aided engineering, design space exploration, crystallography, etc.

LS-DYNA is a general-purpose finite element program capable of simulating complex real world problems. It is used by the automobile, aerospace, construction, military, manufacturing, and bioengineering industries. LS-DYNA is optimized for shared and distributed memory Unix, Linux, and Windows based, platforms, and it is fully QA'd by LSTC. The code's origins lie in highly nonlinear, transient dynamic finite element analysis using explicit time integration.

"Nonlinear" means at least one (and sometimes all) of the following complications:
-Changing boundary conditions (such as contact between parts that changes over time)
-Large deformations (for example the crumpling of sheet metal parts)
-Nonlinear materials that do not exhibit ideally elastic behavior (for example thermoplastic polymers)

"Transient dynamic" means analyzing high speed, short duration events where inertial forces are important. Typical uses include:
-Automotive crash (deformation of chassis, airbag inflation, seatbelt tensioning)
-Explosions (underwater Naval mine, shaped charges)
-Manufacturing (sheet metal stamping)

LS-DYNA's potential applications are numerous and can be tailored to many fields. In a given simulation, any of LS-DYNA's many features can be combined to model a wide range of physical events. An example of a simulation, which involves a unique combination of features, is the NASA JPL Mars Pathfinder landing simulation which simulated the space probe's use of airbags to aid in its landing. LS-DYNA is one of the most flexible finite element analysis software packages available.

LS-DYNA consists of a single executable file and is entirely command line driven. Therefore all that is required to run LS-DYNA is a command shell, the executable, an input file, and enough free disk space to run the calculation. All input files are in simple ASCII format and thus can be prepared using any text editor. Input files can also be prepared with the instant aid of a graphical preprocessor.

There are many third party software products available for preprocessing LS-DYNA input files. LSTC also develops its own preprocessor, LS-PrePost, which is freely distributed and runs without a license. Licensees of LS-DYNA automatically have access to all of the program's capabilities, from simple linear static mechanical analysis up to advanced thermal and flow solving methods. Furthermore, they have full use of LS-OPT, a standalone design optimization and probabilistic analysis package with an interface to LS-DYNA.
