OptiStruct: Design and optimization software using finite elements and multibody dynamics
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 multi-body 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.

RADIOSS: Finite element solver for linear and nonlinear problems
Altair RADIOSS is a leading structural analysis solver for highly non-linear problems under dynamic loadings. It is highly differentiated for scalability, quality and robustness, and consists of features for multiphysics simulation and advanced materials such as composites.
RADIOSS is used across all industries worldwide to improve the crashworthiness, safety, and manufacturability of structural designs. For over 25 years, RADIOSS has established itself as a leader and an industry standard for automotive crash and impact analysis.
In the RADIOSS 2017 release, physics modeling capability has been expanded to include additional advanced material and failure laws. Improved simulation driven innovation was enabled by improvements to solver robustness and accuracy and strong ties to optimization. Computation performance has been improved such that 16300+ cores could be used to simulate a 10 million element full vehicle model. RADIOSS has become even easier to use with the addition of new automated ways to handle poor solid element quality and contact initial intersections. Ease of use was improved with new composite modeling input that better matches the manufacturing process.

MotionSolve: Multibody dynamics solver
Improved workflow for co-simulation using Simulink CoderTM
The workflow for co-simulation between MotionSolve and Simulink® via the Simulink CoderTM has been revised for ease of use. In the current version, you can make use of a script to compile your Simulink CoderTM model into a dynamic linked library.

Faster simulation times while using SI1
The solver has been enhanced to provide faster simulation times when using the DSTIFF integrator with DAE index 1(Stabilized Index 1). The scaling of the Jacobian terms corresponding to constraint equations has been modified. This has resulted in faster simulation times for SI1. Speed improvements between 10-15% are seen on average.

Enhanced gravity modeling
The Force_Gravity modeling element can now be specified as a function expression as well as a real number. This allows you to model gravity as a function of time in your model.

Python user subroutine library
In this release, MotionSolve provides a library of user subroutines written in Python for your reference. These can be accessed at <altair_root>\hwsolvers\motionsolve\usersub\py_src.

Improved error messages
The solver error messaging has been improved in some areas. This enables you to better understand what the solver is doing and it allows you to more easily debug your model. Some of these include:
- Improved error messages if non-matching parenthesis are detected in any function expression
- More understandable messages when redundant constraints are detected in the model
- More understandable messages when a U or V parameter goes out of range in a PTCV, PTdCV, PTSF, PTdSF etc. modeling element
- More understandable messages when a negative stiffness or damping value is specified for a spring damper or bushing modeling element

Modeling check for spring damper, bushing, beam and field elements
Previously, if you specified I and J markers belonging to the same body for the above model elements, MotionSolve would fail during the analysis with little information about the cause. This made debugging the model difficult. Within this release, a mechanism that checks this condition has been implemented. If the I and J markers for the above elements belong to the same body, a relevant error message is printed out and the simulation is stopped.

Visualizing rigid body contact
With this release, the default setting for visualizing rigid body contact forces in HyperView has changed. Now, if rigid body contact is modeled, MotionSolve will always write out rigid body contact information allowing you to visualize the contact force vectors in HyperView. To turn this feature off, you may modify the contact_gra_output attribute within the ResOutput command.

Automotive Extensions to the Solver
MBD – Vehicle Dynamics Tools
The MBD – Vehicle Dynamics Tools in MotionSolve and MotionView are a set of modeling entities for bushings, bump-stops, dampers, rebound-stops, springs and tires that extend the capabilities of MotionSolve
