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.
In friction stir welding, a rotating tool moves along the weld joint and melts the aluminum through the generation of friction heat. The tool’s rotation stirs the melted aluminum such that the two plates are joined. In this model, two aluminum plates are joined by generating friction ... Read More
This model solves the fluid flow and heat transfer in a micro heat exchanger made of stainless steel. These types of heat exchangers are found in lab-on-chip devices in biotechnology and micro reactors, for example for micro fuel cells. The model takes heat transferred through both ... Read More
This example considers the turbulent flow of an oil-water suspension through an orifice. The oil droplets are broken up into smaller droplets by the turbulent stresses as the suspension passes through the orifice. The aim of this model is to track the distribution of droplet sizes. The ... Read More
This example models a oil reservoir with two horizontal wells. The reservoir contains two phases, water and oil. Oil is recovered by injecting water through the bottom well, so the oil production rate and the water-oil production ratio over time are computed. Read More
This example uses the Shallow Water equations to model the impact of a water wave on a column. A body of water with a height of 0.3 meters is initially contained behind a gate. At the start of the simulation, the gate is suddenly released and the body of water forms a wave moving toward ... Read More
In massive forming processes like rolling or extrusion, metal alloys are deformed in a hot solid state with material flowing under ideally plastic conditions. Such processes can be simulated effectively using computational fluid dynamics, where the material is considered as a fluid with ... Read More
Chemical vapor deposition (CVD) is a process often used in the semiconductor industry to grow layers of high-purity solid material on top of a wafer substrate. CVD is achieved using many different techniques and across a range of pressures from atmospheric to ultrahigh vacuum (UHV/CVD). ... Read More
In the semiconductor industry, rapid thermal annealing (RTA) is a semiconductor process step used for the activation of dopants and the interfacial reaction of metal contacts. In principle, the operation involves rapid heating of a wafer from ambient to approximately 1000–1500 K. As soon ... Read More
In general, there are two classes of ventilation: mixing ventilation and displacement ventilation. In displacement ventilation, air enters a room at the floor level and displaces warmer air to achieve the desired temperature. Heating sources in the room can include running electronic ... Read More
This model simulates arc welding of a titanium plate made from an alpha-beta titanium alloy. During a weld pass, the material experiences a thermal transient, including both heating and cooling. Phase transformations are modeled, and the evolution of the phase composition over time is ... Read More
