RADIOSS 2017.2.4 Release Notes

View new features for RADIOSS 2017.2.4.

Highlights
Version 2017.2.4 of RADIOSS fixes critical issues detected in 2017.2.3 release and includes some enhancements.

Finite Volume Airbag (/MONVOL/FVMBAG1)
- Reduction of the starter time for the automatic FVM airbag meshing.
- On win64 machines, behavior improvement of automatic FVM airbag meshing.
- Automatic setting of DTBAG and NFV in /TH/MONV when FVMBAG1 airbag is defined in the model.
- Implementation of heat transfer option in case of airbag temperature is lower than the ambient temperature.
Failure Model /FAIL/TAB1
- Correction of an issue with strain rate dependent instability table.
- New integer flag for selecting the instability or fracture regularization method located in card 4 field 10.
Ch_i_f, Flag for choice of instability or fracture regularization.
= 1 (Default): Element length regularization affects the fracture curve
= 2: Element length regularization affects the instability table
= 3: Element length regularization affects both fracture curve and instability table Material /MAT/LAW19 (FABRI)
- Stability improvement for QEPH and BATOZ shell elements in /PROP/TYPE9 (SH_ORTH).
- To improve stability, the minimum value of the reduction factor RE is 0.001.
Resolved Issues
/INIBRI/STRS_F
Improvement to take into account multiple values coming from /INIBRI/STRS_F cards and other /
INIBRI cards (strain and aux) in the same element.
/DT/THERM
Correction of bug concerning thermal time step and de-blocking limit conditions at the end of thermal run.
//SUBMODEL
Issue with /INISHE/ORTH_LOC and /MONVOL/AIRBAG1.
/ADMAS with type = 3, 4, 6, 7
Important correction and improvement of the mass distribution./INTER/TYPE23
Corrected starter crashes caused by the location of the contact definition in the input model.
/BOX/BOX
Corrected starter crashes for the surface defined with the option /BOX/BOX.

OptiStruct 2017.2.4 Release Notes

What's new and changed in OptiStruct 2017.2.4.
Altair OptiStruct is an industry proven, modern structural analysis solver for linear and non-linear mechanical problems under static, dynamic, and thermal loads. It is the market-leading solution for structural design and optimization. Based on finite-element and multibody dynamics technology, and through advanced analysis and optimization algorithms, OptiStruct helps designers and engineers rapidly develop innovative, lightweight and structurally efficient designs. OptiStruct is used by thousands of companies worldwide to analyze and optimize structures and mechanical systems for strength, durability, noise and vibrations, heat transfer, as well as impact.

2017.2.4 is a bug fix release for OptiStruct. The following issues are fixed in 2017.2.4.

Modal Frequency results could be wrong when the following conditions are met:
- Viscous damping elements (CDAMP, CVISC, CBUSH)
- AMLS or Lanczos
- PARAM,FASTFR or PARAM,FFR is not used
Approximation error from multi-axial fatigue optimization

About Altair HyperWorks. Altair HyperWorks is the most comprehensive, open architecture CAE simulation platform in the industry, offering the best technologies to design and optimize high performance, weight efficient and innovative products. HyperWorks includes best-in-class modeling, linear and nonlinear analyses, structural and system-level optimization, fluid and multi-body dynamics simulation, electromagnetic compatibility (EMC), multiphysics analysis, model-based development, and data management solutions.

About Altair HyperWorks Solvers. HyperWorks Solvers is a collection of finite element and multibody dynamics solvers for structural, fluid-dynamics and systems simulation. These solvers can be employed for simulation driven design as well as design optimization.

With the 13.0 release, a renaming of our structural solver products has taken place in order to accommodate the growing trend of applying optimization technologies more intensively in the product development process, instead of just single run analysis. Moving forward, our structural and thermal analysis and optimization product for linear and non-linear events will be called OptiStruct; this includes analysis disciplines such as linear and non-linear statics, noise and vibrations and thermal analysis. Our product for highly-nonlinear, typically transient events such as crash, impact, forming or blast analysis will be RADIOSS. Both codes are developed with a strong focus on the above mentioned disciplines, and will continue to leverage technology mutually. OptiStruct will continue to leverage the widely used bulk data input format, and RADIOSS will continue to use the well suited block format. Moving forward, OptiStruct will also serve as the general framework for optimization involving multiple physics incl ding CFD and FSI with AcuSolve and multi-body dynamics with MotionSolve, and will also offer API to integrate additional solvers and solutions within a general multi-model framework.

About Altair. Altair is focused on the development and broad application of simulation technology to synthesize and optimize designs, processes and decisions for improved business performance. Privately held with more than 2,000 employees, Altair is headquartered in Troy, Michigan, USA and operates more than 45 offices throughout 22 countries. Today, Altair serves more than 5,000 corporate clients across broad industry segments.
