For a list of such trademark representative, go to other COMSOL websites, request information and pricing, submit technical support queries, subscribe to the monthly eNews email newsletter, and much more. If you define a "Parametric Sweep" with two parameters and give your values as range, then COMSOL will try to use these, but it might not manage to make the solution converge. frequency domain) If you also have parametric sweep, then in should be the top one to cover the other ones with the sweep. It provides an overview of the COMSOL ® environment with examples that show you how to use the COMSOL Desktop ® user interface and the Model Builder. We will also show you how to use the COMSOL software’s Batch Sweeps option, which is a built-in, embarrassingly parallel functionality for improving performance when you reach these limits. The COMSOL Desktop®user interface provides a complete and integrated environment for physics modeling and simulation as well as application design, providing you with the tools necessary to build a user-friendly interface for your models.

Fully coupled multiphysics and single-physics modeling capabilities. Complete modeling workflow, from geometry to postprocessing. User-friendly tools for building and deploying simulation apps. Now available: COMSOL Multiphysics ® version 5.6. Instead of manually changing these property values and re-solving each time, you can perform a parametric sweep with COMSOL Multiphysics ®. A parametric sweep allows you to change the parameter values through a specified range. In this tutorial video, we will teach you how to implement a parametric sweep with the COMSOL ® software. Browse the threads and share your ideas with the COMSOL community. To study both steady-state and transient responses, it helps to define a global parameter t with the unit of time, and a time-dependent generation rate gR using the global parameter t and a global piecewise function pw1, which, in this model, describes a The electric conductivity can be made a function of the spatially varying magnetic field, which we just computed, but we would also like to consider the rotation of the wheel. Functions are generic in COMSOL Multiphysics. Select a Sweep type to specify the type of sweep to perform: Specified combinations (the default) solves for a number of given combinations of values as given for each parameter in the list. 1 Reply Last Post 2013å¹´2月23日 GMT-8 上午4:31. For example, replace the radius of the circle function of time. Guangrui Jiang . One of the core capabilities of the COMSOL Multiphysics® software is the ability to run batch sweeps, where multiple variations of the same model are solved in parallel, but in entirely separate jobs, on the same computer. The parameter lists are combined in the order given, that is, the first combination contains the first value in each list, the second combination contains all second values, and so on. I am trying to use Matlab's Global Optimization tool (specifically using genetic algorithms) with my function based on comsol. Watch the video here.
