Altair MotionSolve Capabilities
Powerful analysis techniques
Although most of the systems are dynamic, the idealization of problems can help in simplifying the problem. Through all different analysis techniques, MotionSolve can help study the mechanical system in different ways.
- Six integrators to solve a large variety of dynamics problems. The integrators include implicit/explicit, stiff/nonstiff and DAE/ODE based algorithms.
- Four Static/quasi-static solvers to predict static equilibrium configurations and loads. The algorithms together cover force imbalance, energy and DAE based methods.
- Kinematic analysis with automatic redundant constraint detection and removal
- Linear analysis with state matrix export and eigenvalue computation.
Rich library of modeling elements
The key enablers for simulating complex mechanisms are the availability and flexibility of advanced modeling elements. MotionSolve supports a huge set of modeling elements that allow users build any complex mechanism.
- Common system-modeling entities
- Mass- and inertia-bearing rigid elements
- Flexible bodies
- Constraint connectors
- Force connectors
- Non-mechanical modeling elements
- Commonly used lower-pair constraints, forces and motion descriptions
- Advanced modeling elements
- Deformable curve
- Deformable surfaces
- 3D contact between tessellated and primitive graphics of any shape
- Flexbody contact using deformable surfaces
- User subroutines to capture complex functions or extend the solver capabilities
Solver customization tools
While most solvers do not support any customization, MotionSolve offers a truly customizable and flexible solution
- Custom functions to support industry or domain specific terminology
- User defined statements for incorporating multiple elements into a single entity
- Customized messaging to extract meaningful solver information and statistics
- Tailoring the solver output format to fit any CAE environment
Direct Integrated with HyperWorks
MotionSolve is a key component in system analysis level studies. Being directly integrated with HyperWorks users get a complete solution from state of the art pre- and post-processing to optimization and robustness studies.
- Multibody models can be built in MotionView as well as the HyperMesh environment
- Perform DOE, optimization and stochastic studies through the direct integrated with HyperStudy
- State of the art post processing using HyperView and HyperGraph
- Finite element based multibody simulation through RADIOSS
- Industry leading system and component optimization through OptiStruct
Open and Flexible Architecture
User performing a system level analysis requires exchanging data with various CAE environments. MotionSolve is highly compatible and thus works with several products seamlessly.
- Unmatched integration between FE and MBD domains through support of the bulk data files (BDF)
- Legacy support for models such as ADAMS (ADM & ACF)
- Co-simulation interface with Simulink
- Embedded co-simulation with hydraulic or pneumatic models from DSHPlus
