MATHEMATICS, SIMULATION AND MODELLING
11 February 2014
Noesis Solutions, which provides simulation software to manufacturers in automotive, aerospace, and other engineering-intense industries has announced the latest release of Optimus (10.13)
The software introduces another three new software interfaces for Siemens NX CAD, Siemens NX CAE and MSC Adams/View. The Optimus 10.12 release added seven new software interfaces; with this new release the total number of software interfaces has reached 26.
Further extensions and performance improvements to existing interfaces add support for the latest PTC Creo Parametric 2.0 and ANSYS Workbench 15.0. In addition, the new release provides support for ANSYS RSM HPC Parametric Pack and parallelisation capabilities for the existing MATLAB interface.
The new direct interface for MSC Adams/View typically facilitates the use of multi-body dynamics to better understand the dynamics of moving parts, or how loads and forces propagate through mechanical systems. By automatically scanning all model parameters and system response metrics defined in the Adams/View command files, Optimus eliminates the need for manual parameterisation and batch mode execution altogether.
Parametric simulation campaigns involving MSC Adams quickly provide a comprehensive data set to be further processed by Optimus’ state-of-the-art Design of Experiments (DOE) and Response Surface Modeling (RSM).
This helps design engineers grasp the unexplored design space potential up-front and acquire deeper insight when evaluating the performance of the proposed design candidates. With Optimus’ support for Adams/View server mode, communication lines with Adams/View remain open throughout the execution of a series of virtual experiments.
Optimus 10.13 includes NX CAD and NX CAE direct interfaces for Siemens NX. Both interfaces support automatic parameter parsing through expressions defined in NX, reducing the need for manual user interaction and parameterisation. Support of NX server mode enables Optimus to launch the Siemens NX software once, and then manage numerous subsequent model adaptations and runs during the simulation and optimisation process.
Thanks to both new interfaces, Optimus enables engineering teams aligned on Siemens NX to steer any simulation sequence toward feasible design candidates designed to deliver superior performance. Major product improvements can be realised in engineering projects involving NX CAD and/or CAE, also benefiting from NX’ powerful interfacing with a wide range of FE solvers such as NX Nastran, Abaqus and LS-DYNA. The Optimus interface for NX CAD also supports custom journal files allowing the definition of any specific user action, such as export to STEP or IGES formats.
Among the upgraded interfaces featured in Optimus 10.13 is the PTC Creo Parametric 2.0 interface. This interface update additionally supports Pro/ENGINEER Wildfire 5.0 as well as Creo Parametric 1.0. With interfaces available for the current versions of PTC Creo Parametric, CATIA V5 and NX CAD, Optimus now fully supports all major parametric 3D CAD solutions. Whatever CAD solution engineering teams are using, Optimus 10.13 ensures a streamlined design process where any changes implemented into the CAD model automatically propagate to downstream CAE models throughout the entire simulation workflow, delivering better results faster than before.
Optimus 10.13 not only supports the ANSYS 15, but also adds support for ANSYS’ scalable solutions for the simultaneous execution of multiple design points (ANSYS 14.5/15). First, Optimus 10.13 supports the ANSYS Workbench-based Remote Solve Manager (RSM). This job queuing system efficiently manages analysis on Windows and Linux operating systems. The RSM enables virtual experiments to be executed simultaneously in the background on local workstations or on remote servers.
There is even more to gain with Optimus’ support of ANSYS HPC Parametric Pack license (ANSYS 14.5/15). This HPC Parametric Pack license delivers scalable parallel processing for single simulation jobs, enabling multiple simultaneous design evaluations with no additional ANSYS application licenses required. This cost-effective solution is very attractive in combination with Optimus parametric analysis and optimisation, reducing both simulation cost and elapsed time.
Optimus 10.13 has also been extended to support parallel execution of multiple MATLAB runs, either using Optimus’ local parallel capabilities, Optimus Parallel Services, or third-party queuing systems. Optimus Parallel Services (introduced with Optimus 10.12) is Noesis Solutions’ new lightweight queuing system that is easy to install and configure in a network environment without advanced IT infrastructure. In any of these MATLAB-involved parallel execution scenarios, Optimus orchestrates the remote execution of inputs substitution, simulations and results extraction.
