The Application Gallery features COMSOL Multiphysics® tutorial and demo app files pertinent to the electrical, structural, acoustics, fluid, heat, and chemical disciplines. You can use these examples as a starting point for your own simulation work by downloading the tutorial model or demo app file and its accompanying instructions.
Search for tutorials and apps relevant to your area of expertise via the Quick Search feature. Note that many of the examples featured here can also be accessed via the Application Libraries that are built into the COMSOL Multiphysics® software and available from the File menu.
This example presents a biomechanical model of the human body for evaluating its dynamic response to vertical vibrations in a seated posture. Such models can be used to predict the response of the human body in vibration environments and have applications in ride quality analysis and the ... Read More
This example illustrates the modeling of a multibody mechanism submerged in a fluid. The mechanism consists of two fins connected to a central rigid body through hinge joints. A transient fluid–structure interaction analysis is performed to simulate the swimming behavior of the ... Read More
This tutorial application demonstrates how to model a hinge joint between two bodies in COMSOL Multiphysics. It also demonstrates various features available for joints, including Constraints, Locking, Spring, Damper, Prescribed Motion, and Friction. Many real structures can be ... Read More
This model illustrates the operation of a swashplate mechanism used in helicopters to translate the input of helicopter flight control into the motion of the rotor blades, and hence controls the orientation of the rotor blades. In this model, the rotor blades are modeled as either rigid ... Read More
A centrifugal governor is used to control the speed of rotating machinery. One of the most common applications is in controlling the RPM of an engine by regulating the fuel supply. This model illustrates the functioning of a spring loaded centrifugal governor. The dynamics of the ... Read More
Many trucks are equipped with cranes for load handling. Such cranes have a number of hydraulic cylinders, controlling the motion, and several mechanisms. The cylinders and mechanisms that make up the crane are subjected to large forces when handling heavy loads. In order to determine ... Read More
This model illustrates the modeling of slider motion caused by a base rotation. The motion of the slider is analyzed under various forces such as inertia force, centrifugal force, spring force and damping force. The prismatic joint, which is used to connect the two components, is spring ... Read More
Most metals and alloys undergo viscoplastic deformation at high temperatures. In the case of cyclic loading, a constitutive law with both isotropic and kinematic hardening is necessary to describe effects such as ratcheting, cyclic softening/hardening, and stress relaxation. The ... Read More
Walking instability due to the nonuniform distribution of clothes is a common problem in lightweight portable washing machines. This problem is more severe in horizontal-axis washing machines, which are widely used because of their high efficiency despite their higher manufacturing ... Read More
Gyroscopes are used to measure orientation or maintain the stability of vehicles such as airplanes, spacecraft, and submarines. They are also used as sensors in inertial guidance systems. This model demonstrates the modeling of a mechanical gyroscope. It analyzes the response of a ... Read More
