Accurate, Robust Analysis for your Industry
AIRBAG DEPLOYMENT
Dytran’s accuracy has been proven through correlation with physical experiments. Dytran helps engineers predict how a prototype would respond to a variety of real-world dynamic events and to examine potential causes for product failure. Some industry application examples include:
Unique Combination of Simulation Technologies
HYDROPLANING
MORTAR LAUNCH
Dytran’s innovative ability to model the interaction of adaptive, multiple Eulerian domains around coupling surfaces as they move and deform gives you the power to analyze complex FSI scenarios that are often too difficult or impossible to simulate with other software tools, such as:
Dytran for Maximizing Productivity
RAMJET
BLAST UNDER VEHICLE
Through continuous enhancements, Dytran has delivered productivity improving capabilities with each new release. Some of the recent technology enhancements include:
Transient Structural Analysis (Crash/Impact)
FAN BLADE OUT
BOTTLE MANUFACTURING
Dytran uses explicit technology to solve transient dynamic problems. Solid, shell, beam, membrane and connectors and rigid elements can be used to model the structures. A wide range of material models are available to model the nonlinear response and failure. These include linear elasticity, yield criteria, equations of state, failure and spall models, explosive burn models and composite materials to name a few. Contact surfaces allow structural components to interact with each other or with rigid geometric structures. This interaction may include frictionless contact, sliding with frictional effects and separation. Single surface contact can be used to model buckling of structures where material may fold onto itself.
Fluid-structure Interaction
CONTAINER DROP TESTING
SLOSHING
Eulerian solvers are typically used for solving fluid problems, while Lagrangian solvers are used to solve structural problems. However, many real world situations need to account interactions between fluids and solids – deforming solids affecting fluid flow and fluid flow deforming a structure. Problems like fluid sloshing in a tank, airbag inflation, hydroplaning etc. can only solved with fluid-structure interaction accounted for.
Both Lagrangian and Eulerian solvers are available in Dytran to enable modeling of both structures and fluids in a single model and simulate the interaction between them. Interaction between the fluids and structures is achieved through a coupling surface created on structures (Lagrangian domain).
High Performance Computing
Dytran makes use of the latest numerical methods and high performance computer hardware. It provides cost-effective solutions on the latest generation of computers ranging in size from desktop machines to supercomputers. In addition, some applications can exploit the parallel processing facility for distributed memory systems.
