非线性瞬态动力学和瞬态流固耦合问题的数值仿真工具

MSC

.

Dytran

是 MSC.Software 公司的核心产品之一, 适用于瞬态非线性动力问题、瞬态流固耦合问题的数值仿真。从 1988 年开始, MSC 在结构瞬态动力响应软件 DYNA3D 框架下开发了 MSC.Dyna 并于 1990 年发布了第一个版本。该程序继承了 DYNA3D 优异的快速显式积分算法和丰富的材料模式, 采用 MSC.Nastran 的输入数据格式, 可用于分析各种非线性瞬态响应, 如高速撞击、接触摩擦、冲压成型等。

1993 年 MSC 发布了 MSC.Dytran 的第一个商业版本。该产品集 MSC.Dyna 和 MSC.PISCES 3D 之大成, 拉格朗日和欧拉算法优势互补, 成为第一个能够模拟复杂流固耦合问题、高度非线性、瞬态动力响应的大型商用软件，适合于模拟国防军工领域常见的爆炸、穿甲等流固耦合问题, 在国防、航空航天、核安全、石化等领域有广泛应用。在随后的发展中, MSC.Dytran在单元库、数据结构、前后处理等方面与 MSC 的旗舰产品 MSC.Nastran 趋于一致。

在问世的十余年中, MSC.Dytran 历经无数航空、 航天、 汽车、造船、铁路、国防、核工业等领域科研和工程项目考验。该软件的开发环境经过 ISO 认证, 每天都要通过 500 个以上例题的自动测试以保证程序的可靠性和稳定性。2003 年 MSC.Software 公司与 LSTC 公司达成全球战略合作协议，将 LS-DYNA 程序完全集成入 MSC.Dytran。此功能在 Windows, UNIX 和 Linux 操作系统上均可方便实现。计算高效，求解稳定。MSC 将最强的 Lagrange 技术与最强的 Euler、耦合技术相结合，形成功能最为强大的非线性显式有限元软件。

MSC Software Corporation, the leader in multidiscipline simulation solutions that accelerate product innovation, announced the new release of Dytran 2013, software program for simulating and analyzing extreme, short-duration events involving the deformation of structural materials and the interaction of fluids and structures.

Dytran is an explicit finite element analysis (FEA) solution for simulating short-duration events like impact and crash, and to analyze the complex nonlinear behavior that structures undergo during these events. Dytran enables you to study the structural integrity of designs to ensure that final products stand a better chance of meeting customer safety, reliability, and regulatory requirements.

Dytran delivers a structural, material flow and coupled FSI analysis capabilities in a single package. Dytran uses a unique coupling feature that enables integrated analysis of structural components with fluids and highly deformed materials in one continuous simulation.

Dytran 2013 is the latest and most comprehensive version of Dytran released by MSC Software, bringing new simulation technology and improved performance.

Dytran 2013 includes major new capabilities that are primarily focused in the areas of High Performance Computing (HPC) for fluid-structure interaction (FSI) applications resulting in dramatic performance improvement for CPU intensive simulations. These are:

- 1-D to 3-D Spherical Symmetry and 2-D to 3-D Axial Symmetry Remapping for blast loads

- Enhancements to Coupling and Clumping algorithms to improve the Distributed Memory Parallel performance of FSI applications.

- New interface to USA code for Underwater Shock Explosion applications.
