Dytran is an explicit finite element analysis (FEA) solution used by leading engineers across the globe to simulate short-duration events like crash and impact and analyze complex non-linear behaviour changes in structures due to such events. It can be leveraged to study the structural integrity of designs so that the final product can meet the expected customer safety, reliability, and regulatory requirements.

Dytran is a comprehensive package providing structural, material flow and coupled fluid structure interaction capabilities in a single solution. The unique coupling feature in Dytran enables integrated analysis of highly deformed materials and structural components with fluids in a continuous simulation.

Key Features

Industry-specific Accurate Analysis

Dytran is the foremost FEA solution for engineers intending to predict a prototype’s response under real-time dynamic events. Widely appreciated for its accuracy proven through correlation with physical test results, Dytran assists engineers in examining potential causes of product failure. With its robust features, Dytran has found wide-scale implementation avenues in the aerospace, automotive, military, and defense applications by providing accurate, industry-specific analysis. Sports equipment impact analysis, drop testing, bottle, container, paper feeding and packaging design are some of the other vital applications of Dytran.

Unique Combination of Simulation Technologies

Dytran has the pioneering ability to model the interaction of adaptive, multiple Eulerian domains around coupling surfaces as they move and deform which empowers engineers to analyse complex FSI scenarios that are almost impossible to simulate with other tools. Dytran is extremely effective in simulating scenarios such as multiple objects impacting multi-layered structures, massive structural failure with fluid leakage or penetration, as well as fluid filling and sloshing within an enclosed volume.

Dytran for Maximizing Productivity

We are committed to delivering feature-rich capabilities with each new release of Dytran for maximizing efficiency, and productivity. Some of the latest feature enhancements include Coupling surface computation; Distributed Memory Parallel capability of Eulerian solver; Cyclic flow boundary to optimize model sizes in turbine simulation, pipe-flow simulation; Body forces that can be applied on different materials inside a particular region, Grade mesh for Euler and non-uniform Euler mesh offering greater modeling flexibility; Time step determination to accelerate axi-symmetric mesh models; Special boundary treatment definition based on the hydrostatic pressure profile.

Transient Structural Analysis

Dytran is quite effective in solving transient dynamic problems with a host of explicit technologies. To model the nonlinear response and failure, engineers may choose from the wide array of material models available such as linear elasticity, yield criteria, equations of state, failure and spall models, explosive burn models and composite materials, etc. Structural component interactions such as frictionless contact, sliding with frictional effects, and separation can be manifested on contact surfaces. On the other hand, single surface contact can be leveraged to model buckling of structures.

Fluid-Structure Interaction

Though there are different solvers available to address fluid and structural problems individually, several real-time scenarios need to take into account the interactions between fluids and solids – such as deformation of solid affecting fluid flow and fluid flow deforming a structure. Fluid sloshing in a tank, hydroplaning, and airbag inflation are some of the classic challenges which require the fluid-structure interaction to be taken into consideration.

Dytran comes with both Lagrangian and Eulerian servers that enable the modeling of both fluids and structures in a unified model. A coupling surface created on structures (Lagrangian domain) can be leveraged to simulate the interaction between fluids and structures very effectively.

High-performance Computing

Enabled with the latest numerical methods and high-performance computer hardware, Dytran is the ultimate solution for engineers looking for cost-effective solutions for the latest generation computers, from desktops to supercomputers. Certain applications can leverage the parallel processing facility for distributed memory systems as well.
