Comsol Multiphysics 5.2a Update2 (x64) | 4.3 Gb
COMSOL, the leading provider of multiphysics modeling and simulation software, has released update2 for version 5.2a of COMSOL Multiphysics software, is a general-purpose software platform, based on advanced numerical methods, for modeling and simulating physics-based problems. COMSOL software version 5.2a update 2 contains performance and stability improvements to COMSOL Multiphysics, COMSOL Server, and COMSOL Client, as well as a small set of additional new features. As part of this update release, the new Rotordynamics Module is available as an optional add-on to the Structural Mechanics Module.
Performance Improvements in COMSOL Version 5.2a Update 2
COMSOL versions 5.2a, 5.2a update 1, and 5.2a update 2 provide significant performance improvements compared to version 5.1 and earlier versions. These performance improvements are most notable with respect to the handling of models with several thousand domains, boundaries, edges, and points. The following table shows the most important of these performance improvements and the estimated speedup for the handling of large models.
New Product in COMSOL Version 5.2a Update 2: The Rotordynamics Module
You can use the Rotordynamics Module, which is an optional expansion to the Structural Mechanics Module, to analyze the effects of lateral and torsional vibrations of rotating machinery in order to study rotor vibrations and contain their levels within acceptable design limits. The different design parameters you can evaluate with this module include critical speeds, whirl, natural frequencies, stability thresholds, and the stationary and transient responses of a rotor due to mass unbalances. You can also see how rotational behavior may lead to stresses in the rotor itself, as well as additional loads on and vibration transmissions to other parts of the rotating machine's assembly.
With the Rotordynamics Module, you can take into account the effects of various stationary and moving rotor components, including disks, bearings, and foundations. You can also easily postprocess your results directly within the software environment, presenting them as Campbell diagrams, modal orbits, harmonic orbits, waterfall plots, and whirl plots.
New Functionality in COMSOL Version 5.2a Update 2
- Support for macOS Sierra
Continuing its commitment to the Mac user community, update 2 now includes support for macOS Sierra (version 10.12).
- Waterfall Plot
Use the new Waterfall plot to create a diagram of how an expression depends on two parameters in a parametric sweep. For example, in the Rotordynamics Module, this type of plot can be used to show the displacement at a point of a rotor versus displacement at different rotor speeds and natural frequencies.
- Whirl Plot
Use the Whirl plot to create a plot of the modal shapes of a beam rotor that is rotated about the rotor axis at discrete rotation intervals. This plot type requires the Rotordynamics Module.
- Cluster and Batch Computing Preferences
The Cluster Computing, Cluster Sweep, Batch, and Batch Sweep study steps have a new option to control low-level settings from the Preferences window. This functionality is available in new Cluster Computing settings and Remote Computing settings, where you can choose between User controlled and Preferences controlled.
- Stop Time for Batch Jobs
When running a batch job from the operating system command line, you can now automatically stop a job after a given amount of time. This functionality is available by a new command-line option, stoptime, which allows you to specify a stop time value in seconds.
- Mass Transport in Fractures
In the Chemical Reaction Engineering Module, a new Fracture feature is available that can be used to solve for porous media transport along boundaries. The new functionality has been added to the Transport of Diluted Species interface.
- New Time to Frequency FFT Study for Heat Transfer
A new study type, Time to Frequency FFT, is now available for all heat transfer interfaces. This study type is used to transform a time domain solution into a frequency domain solution by means of a fast Fourier transform (FFT).
- Solar Irradiance for Ambient Settings
A new Infinite distance option is available for Solar Irradiance, as used in the Ambient Settings for an External Radiation Source.
COMSOL provides simulation software for product design and research to technical enterprises, research labs, and universities through 18 offices and a distributor network throughout the world. Its flagship product, COMSOL Multiphysics, is a software environment for modeling and simulating any physics-based system. A particular strength is its ability to account for coupled or multiphysics phenomena. Add-on products expand the simulation platform for electrical, mechanical, fluid flow, and chemical applications. Interfacing tools enable the integration of COMSOL Multiphysics simulation with all major technical computing and CAD tools on the CAE market.
