MSC Dytran 2025.2

MSC.Dytran is a system for analyzing highly nonlinear fast-moving processes associated with the interaction of various parts of a structure, a structure and a structure, as well as a structure and a liquid (gas).

MSC.Dytran is a system for analyzing highly nonlinear fast-moving processes associated with the interaction of various parts of a structure, a structure and a structure, as well as a structure and a liquid (gas).

Typical applications of MSC.Dytran include the interaction of a vehicle, an obstacle, a passenger, and an airbag during its inflation during a crash, bird strikes on aircraft structures, ship collisions and groundings, explosions in confined spaces, projectile impacts on and through barriers, meteorite impacts on spacecraft skins, metal stamping, fluid behavior in partially filled containers, and other problems.

MSC.Dytran is based on an explicit method for integrating differential equations over time. This eliminates the need for decomposing large matrices, which consumes a significant portion of processor time when solving highly nonlinear problems. The program is fully vectorized and can be effectively used on computers supporting parallel data processing.
The technology for solving nonlinear structural dynamics problems is based on developments originally performed at Lawrence Livermore National Laboratory. Algorithms for modeling the interaction between a structure and a fluid (gas) originate from developments by the Dutch company Pisces International (acquired by MSC in 1990), subsequently developed by MSC.Software Corporation. To solve such problems, MSC.Dytran uses the Euler formulation.
Due to its ability to solve highly nonlinear problems in the analysis of heterogeneous media, MSC.Dytran is effectively used in the automotive, aerospace, defense, and other industries.
