Comsol 5.2 download

It allows users to create, run, and analyze multiphysics models that can include any combination of electrical, mechanical, comsol 5.2 download, fluid, chemical, and acoustic phenomena. COMSOL Multiphysics can also be used to build and deploy simulation applications that can be accessed by anyone through a web browser or a dedicated client. In this article, we will review some of the new features and improvements that were introduced in version 5.

All of these improvements are listed in the Update Details tab below. This software update is cumulative in that it applies to version 5. If you have version 5. If you have a version older than version 5. A file in the MPH format that has been saved using version 5. As of update 2, the new Rotordynamics Module is available as an optional add-on to the Structural Mechanics Module.

This update corrects a few bugs and stability issues in Version 5. In some browsers, such as Internet Explorer, you get a dialog box where you can click Run directly after download. In other browsers, such as Chrome, you have to select the downloaded file and run it, see step 3 below. Run the downloaded. Unpack it by the commands:. Double-click the downloaded. Log Out Log In Contact. Windows Run the downloaded. Linux Copy the downloaded. Unmount the disk image. Check that the version number is 5. If not, the installation did not succeed. Fixed an error in the reinitialization of particle velocity components when using the "Diffuse reflection" Wall condition in 2D axisymmetric models with out-of-plane degrees of freedom. A problem with the initialization of particle velocity and auxiliary variables using data imported from two or more text files in a single physics interface has been corrected. Stability improvements Ray Optics Module Fixed an error caused by using the Illuminated Surface release feature while the Compute phase check box is selected in the settings window for the Geometrical Optics physics interface.

Whirl plots are used in the analyses of rotating machine rotors that are simulated comsol 5.2 download beam elements. The following table shows the most important of these performance improvements and the estimated speedup for the handling of large models.

.

This saves memory and computing power when you only need part of the solution for visualization and results. This example model shows how an object is detected by radar, using perfectly matched layers to absorb outgoing waves without reflecting them. With this new functionality, you can discard the solution in the perfectly matched layer and only store the solution in the space surrounding the boat, reducing the size of the solution from MB to MB. Size reduction can be even more significant for certain models. RK34 combines adaptivity with good stability properties along the imaginary axis, suitable for oscillatory problems. Cash-Karp is similar to the Dormand-Prince 5 solver added with an earlier version of the software , but has an even larger stability region along the negative real axis, which is more efficient for naturally damped problems.

Administrators can optimize specific app load times by choosing to preload them via the new Prelaunching section of the preferences page. The Prelaunching section, located on the Preferences page. With this option enabled, users do not need to use the Application Library first; the selected app is launched as soon as they log in. View screenshot ». You can now reconnect to a previously launched app. Applications listed under Running Applications feature a unique session ID, a stop button to permanently close the app session, and a drop-down menu offering two reconnect options: in a browser or using COMSOL Client.

A waterfall plot showing the displacement of one of the bearings. 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. New option to use external nonlinear magnetic material models from user-defined dynamic libraries in magnetic fields simulations. Version 5. External Stress-Strain Relation now defines also second Piola-Kirchhoff stresses as postprocessing variables Contribution to Mass Properties from Added Mass in 2D has been corrected The solver for Linearized buckling now computes only one buckling mode as default The accuracy of the slip velocity when contact and friction are used together with the generalized alpha time stepping algorithm has been significantly improved A problem where the rotations in the Shell interfaces could be erroneous over an edge where the adjacent boundaries had different normal directions has been corrected A problem in the definition of slip variables for contact with friction has been corrected in the Solid Mechanics interface. In other browsers, such as Chrome, you have to select the downloaded file and run it, see step 3 below. Some of the major upgrades included:. Stability improvements. With the Rotordynamics Module , you can take into account the effects of various stationary and moving rotor components, including disks, bearings, and foundations. If not, the installation did not succeed.

Users can also build and deploy simulation apps using the Application Builder and COMSOL Server, which can be accessed by anyone through a web browser or a dedicated client. 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. A problem with the initialization of particle velocity and auxiliary variables using data imported from two or more text files in a single physics interface has been corrected. 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. This plot type requires the Rotordynamics Module. Fixed an error caused by using the Illuminated Surface release feature while the Compute phase check box is selected in the settings window for the Geometrical Optics physics interface. Waterfall Plot Use the new Waterfall plot to create a diagram of how an expression depends on two parameters in a parametric sweep. If not, the installation did not succeed. The following table summarizes the main differences between the installation procedures for each platform:.
