In the RF Module, a set of new ports for vias and transmission lines makes setup much quicker and gives more control to the user for modeling of printed circuit boards.Д®fficient Distribution of Standalone ApplicationsД¬OMSOL Compiler enables you to create standalone applications based on COMSOL Multiphysics models with specialized user interfaces that have been built with the Application Builder. Combining the AC/DC Module and the Composite Materials Module, users can now analyze layered materials with both dielectric and piezoelectric layers in thin structures. This enables multiscale modeling, such as analyzing a waveguide beaming into a large room, where using a full-wave simulation would be computationally prohibitive. The Ray Optics Module can now be combined with the RF Module or Wave Optics Module for simultaneous full-wave and ray tracing simulations. Multiscale Wave and Ray Optics, Piezoelectric Shells, and PCB Ports Radiation in semitransparent (participating) media now supports multiple spectral bands, and a new open boundary formulation for convective flow reduces solution time by 30%. The Heat Transfer Module comes with a new interface for lumped thermal systems, an equivalent circuit modeling approach for heat transfer simulations. In addition, the flow interfaces for rotating machinery now support the level set and phase field methods as well as EulerвЂ“Euler and bubbly flow. Users of the CFD Module will get new interfaces for compressible Euler flow and nonisothermal large eddy simulations (LES). The Multibody Dynamics Module provides new functionality for analyzing rigid and elastic chain drives with automatic generation of the large number of links and joints needed for modeling chain drives.Д¬ompressible Euler Flow and Nonisothermal Large Eddy Simulations The loads can be fully correlated, uncorrelated, or have a specific user-given correlation. This allows users to include loads that are random in nature, such as turbulent wind gusts or road-induced vibrations on a vehicle. Users of the Structural Mechanics Module can now perform random vibration analysis to study the response to loads that are represented by their power spectral density (PSD). The new functionality can handle a variety of pipe cross sections and can include effects from external loads, internal pressure, axial drag forces, and temperature gradients through the pipe wall. Depending on the type of analysis, these improvements will be available to users of the Structural Mechanics Module, Nonlinear Structural Materials Module, and Composite Materials Module.ДЇor users of the Structural Mechanics Module, a new user interface for pipe mechanics provides functionality to perform stress analysis of pipe systems. The mechanical contact modeling functionality has been extended to support any combination of solids and shells, including solid-shell, solid-composite shell, and membrane-shell. Nonlinear Shell Analysis, Pipe Mechanics, and Random Vibration AnalysisДЄ wide range of nonlinear analysis options are now available for shells and composite shells, including plasticity, creep, viscoplasticity, viscoelasticity, hyperelasticity, and mechanical contact.
