MSC Nastran, Patran 2016 for CAE Released

NEWPORT BEACH, CA, USA, Jun 19, 2016 - MSC Software Corporation announced new releases of MSC Nastran and Patran. MSC Nastran 2016 delivers dramatic performance and speed improvements as well as new multidisciplinary analysis solutions. Patran 2016 improves support for nonlinear and fatigue analysis capabilities.

Release highlights of MSC Nastran:

Performance

• MSC Nastran 2016 uses enhanced Automated Component Mode Synthesis (ACMS) method with Shared Memory Parallel (SMP) computing delivering better performance and ability to effectively use more cores for higher user productivity. 50% parallel efficiency has been observed for 16 processors. SMP Parallelization can now be used to reduce the overall wall time stiffness matrix computations and stress recovery. 75% parallel efficiency has been achieved with 4 threads with the job running 3 times faster than with one processor.
• Availability of Intel MKL Pardiso solver has been extended to provide better scalability, thereby lowering the overall elapsed time of simulations.

3D Rotor Dynamics

• With the new 3D modelling capability, users can now model discrete blades and non-symmetric components of rotors and stators of rotating machinery, turbines and jet engines improving the accuracy of the rotor dynamic analyses. This type of modelling was not possible with 1D or 2.5D modelling solutions. With 3D modelling, engineers can now see what is happening locally at each blade or at the component level.

Dynamics and NVH

• Equivalent Radiated Power (ERP) can now be output for higher order shell and solid elements. It is also possible to output velocity normal to the surface and vibration intensity.
• Multiple load vectors produced by Actran can now be selectively incorporated in MSC Nastran's frequency response analysis.
• Efficiency of large poroelastic material simulations is improved with access to out-of-core solver of Actran.

Optimization

• New in this release is Global Optimization (GO) which combines automatic multi-start global methods and gradient based local optimization methods. This approach searches the complete design space for the best possible solutions. The new capability was implemented to help automotive and aerospace companies to lightweight safely while optimizing their designs.
• Multi-model optimization (MMO) provides the ability to process separate design models with different topology or analyses to perform combined optimization. This capability is enhanced to solve larger problems and without limit on the number of models.

MSC Nastran Embedded Fatigue

• To maintain consistency with other fatigue solvers, nodal averaged stresses and strains are used for faster computation speed and a more realistic fatigue damage factors.
• Skinning is implemented to create a 2D stress state on the surface of the model leading to fewer calculation points and enabling multi-axial assessments and correction on 3D solid elements.

Advanced Nonlinear

• Beam contact is implemented with segment-to-segment contact algorithm and support for general beam cross section, tube-in-tube contact, including beam offsets, reducing computational cost and providing better accuracy.
• Interference fit analysis common to engineering applications is enhanced to handle large interferences/overlaps.

Explicit Analysis

• Three new models have been introduced to simulate complex material behaviour, namely, a time dependent viscoelastic creep model, Thermo-elasto-viscous plastic creep model, and Riedel-Hiermaier-Thoma model for concrete materials.
• Adaptive solid elements that transform to SPH particles which can help simulate the effects of debris after element failure

Results

• In addition to the existing result formats, MSC Nastran 2016 introduces a new results database based upon the HDF5 standard, which is an open format that will allows easier access via public viewers, Python, Java or C++.
• A new utility is available to provide output file data in easier to read format.

Open Design Alliance Releases Teigha 4.0

PHOENIX, AZ, Jun 22, 2014 - Open Design Alliance (ODA) announced the release of version 4.0 of Teigha, its software development platform for engineering applications.

Version 4.0 contains the alpha release of Teigha Cloud, ODA's new framework for cloud-based rendering of .dwg and .dgn files. Teigha Cloud allows ODA members to take full advantage of cloud-based computing resources and give their customers easy access to extensive information and powerful processing from small, inexpensive mobile devices with limited storage capacity.

By providing ODA members with a strong foundation for building cloud-based apps, Teigha Cloud minimizes time-consuming development. Crucially, it also gives members the freedom to deploy the applications they develop as they choose. With Teigha Cloud there is no obligation to buy into a specific hosting service and no risk of a third party locking up stored data.

"ODA's cloud strategy differs from most other companies in that our goals are openness and flexibility," said Neil Peterson, CTO of the ODA. "We are giving our members complete control so they can, for example, host applications themselves or deploy them on partner or customer sites."

Using Teigha Cloud, drawing files are stored on a remote server and can be accessed by a lightweight client within any WebGL-compatible browser. Standard rendering functions include zoom, pan, 3D rotation, visual styles, selection and layer control.

Teigha 4.0 also contains enhanced support for mobile platforms, including Java support for Android and improvements to Android and iOS rendering.

"Cloud technology is a key focus for us, but it's not a panacea," continues Peterson. "Native apps are the preferred choice for many situations, and Teigha fully supports native development on iOS and Android. Our aim is to provide choice for our members, and allow them to pick the right technology to meet their needs."

In addition Teigha 4.0 contains fixes for more than 400 member-reported issues. Teigha version 4.0 is available for download by ODA members at www.opendesign.com. A demo version of Teigha Cloud is available on the ODA member portal.
