Comsol Multiphysics 5.5 general review

Powerful Parametric Sketching with Dimensions
The Design Module provides a new sketching tool that makes it easy to assign dimensions and constraints to planar drawings for 2D models and 3D work planes.


New Solver Technology for Acoustics Simulations
Ultrasound technology is becoming increasingly important in a wide range of applications spanning from process engineering and nondestructive testing to consumer electronics. New functionality based on the time-explicit discontinuous Galerkin method enables efficient multicore computations of ultrasound propagation in solids and fluids, including realistic materials featuring damping and anisotropy. The method also has low-frequency applications, such as in seismology. The included multiphysics capabilities can seamlessly combine linear elastic wave propagation in a solid and its transition to a fluid as an acoustic pressure wave, and back again. The new elastic wave functionality is available for users of the Structural Mechanics Module, MEMS Module, and Acoustics Module. The fluid-structure acoustics coupling is available in the Acoustics Module.


For frequency-domain simulations, a specialized solver for wave propagation analysis makes it possible to handle higher frequencies (shorter wavelengths) using the finite element method. The new solver can be used to analyze enclosed structures such as that of a car cabin interior as well as other acoustics simulations.

Introducing the Metal Processing Module
The new Metal Processing Module makes metal phase transformation analysis accessible within the COMSOL Multiphysics environment for applications within welding, heat treatment, and metal additive manufacturing.


Introducing the Porous Media Flow Module
The Porous Media Flow Module gives users within, for example, food, pharmaceutical, and biomedical industries a wide range of transport analysis capabilities for porous media. The new add-on product includes functionality for single- and multiphase flow in porous media, drying, and transport in fractures. The flow models cover linear and nonlinear flow in saturated and variably saturated media with special options for slow and fast porous media flows. The multiphysics simulation capabilities are extensive, with functionality that includes options for calculating effective thermal properties for multicomponent systems; poroelasticity; and transport of chemical species in solid, liquid, and gas phases.


Simplified Shape and Topology Optimization with the Optimization Module
Users working with mechanical, acoustics, electromagnetics, heat, fluid, and chemical analysis have been able to perform shape and topology optimization in COMSOL Multiphysics for many years. The Optimization Module now offers simplified setup of shape optimization with new built-in features such as moving boundaries parameterized by polynomials and built-in support for shell thickness optimization. A new smoothing operation for topology optimization ensures higher-quality geometry outputs that can be used for additional analysis and additive manufacturing. COMSOL Multiphysics now has general support for import and export of the additive manufacturing formats PLY and 3MF, in addition to the STL format that is already available.


Nonlinear Shell Analysis, Pipe Mechanics, and Random Vibration Analysis
A wide range of nonlinear analysis options are now available for shells and composite shells, including plasticity, creep, viscoplasticity, viscoelasticity, hyperelasticity, and mechanical contact. 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. 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.

For users of the Structural Mechanics Module, a new user interface for pipe mechanics provides functionality to perform stress analysis of pipe systems. 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.
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).

This allows users to include loads that are random in nature, such as turbulent wind gusts or road-induced vibrations on a vehicle. The loads can be fully correlated, uncorrelated, or have a specific user-given correlation.

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.


Compressible Euler Flow and Nonisothermal Large Eddy Simulations
Users of the CFD Module will get new interfaces for compressible Euler flow and nonisothermal large eddy simulations (LES). In addition, the flow interfaces for rotating machinery now support the level set and phase field methods as well as Euler–Euler and bubbly flow. The Heat Transfer Module comes with a new interface for lumped thermal systems, an equivalent circuit modeling approach for heat transfer simulations. Radiation in semitransparent (participating) media now supports multiple spectral bands, and a new open boundary formulation for convective flow reduces solution time by 30%.

Multiscale Wave and Ray Optics, Piezoelectric Shells, and PCB Ports
The Ray Optics Module can now be combined with the RF Module or Wave Optics Module for simultaneous full-wave and ray tracing simulations. This enables multiscale modeling, such as analyzing a waveguide beaming into a large room, where using a full-wave simulation would be computationally prohibitive. 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. 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.

Efficient Distribution of Standalone Applications
COMSOL Compiler enables you to create standalone applications based on COMSOL Multiphysics models with specialized user interfaces that have been built with the Application Builder. Compiled applications require only COMSOL Runtime — no COMSOL Multiphysics or COMSOL Server license is required. “Since the release of COMSOL Compiler last fall, we have seen great response from our Application Builder users with this new possibility of distributing their applications in standalone form,” said Daniel Ericsson, application product manager at COMSOL. The latest version of COMSOL Compiler has a new compile option for generating minimum-sized files for easier distribution. When the user launches an application for the first time, where the new compile option has been used, COMSOL Runtime is downloaded and installed, if needed, from COMSOL’s website. Only one instance of COMSOL Runtime is needed for applications using the same COMSOL version. COMSOL Runtime has a size of about 350 MB and an application file can be as small as a few MB.

About Comsol Multiphysics 5.4. Its the latest release of its integrated environment for creating physics-based models and simulation applications. Version 5.4 marks the debut of the COMSOL Compiler for creating standalone COMSOL Multiphysics applications. Also new is the Composite Materials module for modeling layered materials.

The new COMSOL Compiler enables simulation specialists to create and distribute standalone executable COMSOL Multiphysics applications. The company explains that neither COMSOL Multiphysics nor a COMSOL Server license are required to run a compiled application. Developers can distribute applications with no further license fees.

The new Composite Materials module provides a dedicated set of modeling tools for working with layered materials. The company adds that by combining the Composite Materials module with new functionality for layered shells available in the COMSOL Heat Transfer and AC/DC modules, users can perform multiphysics analysis such as Joule heating with thermal expansion.

COMSOL Multiphysics version 5.4 also introduces numerous productivity improvements such as the ability to use multiple parameter sets in a model, including parametric sweeping over multiple parameter sets. Users can now also organize Model Builder nodes into groups and assign custom coloring schemes to geometry models. Among the various performance improvements is an updated memory allocation scheme that, the company says, gives several times faster computations in the Windows 7 and 10 operating systems for workstations with more than eight processor cores.

The AC/DC module features a new part library with fully parametric and ready-to-use coils and magnetic cores. The Computational Fluid Dynamics (CFD) module sees added functionality for large eddy simulations (LES) and, according to the company, significantly updated modeling tools for multiphase flow. Fluid flows also see functionality that enable fluid-structure interaction (FSI) for multiphase flow and multibody dynamics.

Electromagnetics enhancements include structural-thermal-optical-performance (STOP) analysis for ray optics. Structural simulations now provide shock response spectrum analyses and offer material activation for additive manufacturing. The Acoustics module sees acoustic ports and a new nonlinear acoustics Westervelt model.

Other version 5.4 highlights include a new topology optimization tool, new lumped models for batteries as well as an updated thermodynamics interface. Heat transfers now features heat radiation with diffuse-specular reflections and semi-transparent surfaces as well as a light-diffusion equation.

In this video, we show you how to model a dipole antenna in the COMSOL Multiphysics software. After watching this video, you will have a solid foundation for creating models of more complex antenna geometries, as the process for building different antenna models is essentially the same.
