Virtual Operations on a Wheel Rim Geometry

This tutorial shows how to perform virtual geometry operations on an imported CAD geometry. These virtual operations, such as form composite entities or ignore entities can help to improve the mesh and reduce the total element number. Читать дальше

Thermal Microactuator Simplified

This example model consists of a two-hot-arm thermal actuator made of polysilicon. The actuator is activated through thermal expansion. The temperature increase required to deform the two hot arms, and thus displace the actuator, is obtained through Joule heating (resistive heating). The ... Читать дальше

The KdV Equation and Solitons

The Korteweg-de Vries (KdV) equation models water waves. It contrasts sharply to the Burgers equation, because it introduces no dissipation and the waves travel seemingly forever. Solitons have their primary practical application in optical fibers. Specifically, a fiber’s linear ... Читать дальше

Electric Sensor

This is a model from electric impedance tomography, a method of imaging the interior permittivity distribution of a body by measuring current and voltage at the surface. This model demonstrates how the shape and placement of figures with different material properties inside a closed ... Читать дальше

Micromixer

The development of mixers does often not only have to account for effectiveness, but also other factors must be involved, such as cost and complexity for manufacturing. The three models study a laminar static micro mixer with two parallel sets of split-reshape-recombine mixing elements. ... Читать дальше

Eigenvalue Analysis of a Crankshaft

This model describes a modal analysis of a crankshaft. The pistons’ reciprocating movement is transferred to the crankshaft through connecting rods by means of crankshaft throws. The forces, torques, and bending moments, which are highly variable both in time and space, subject the ... Читать дальше

Tapered Cantilever with Two Load Cases

This example shows a 2D plane stress model of a thin tapered cantilever. Different boundary and load scenarios are examined. It is demonstrated how to apply and how to evaluate different load and constraint groups. Resulting stresses are compared to NAFEMS benchmark values and they are ... Читать дальше

Steady-State 1D Heat Transfer with Radiation

The example shows a 1D steady-state thermal analysis including radiation to a prescribed ambient temperature. The temperature field from the solution of this benchmark model is compared with a NAFEMS benchmark solution. Читать дальше

Pacemaker Electrode

This model illustrates the use of COMSOL Multiphysics for modeling of ionic current distribution problems in electrolytes, in this case in human tissue. The problem is exemplified on a pacemaker electrode, but it can be applied in electrochemical cells like fuel cells, batteries, ... Читать дальше

Shell Diffusion in a Tank

A goal for many applications is to predict physics in thin structures, such as shells, without modeling the thickness of the structure. This is because large aspect ratios can cause meshing and geometry analysis problems. This model demonstrates how to use the tangential derivative ... Читать дальше
