This model simulates a holographic page data storage system. The studies include the recording and retrieval processes. The object beam encrypting 8-bit data is focused into a holographic material by a Fourier lens (Fourier transformation). In the recording process, the object beam ... Read More
Mechanical precession prevents bicycle pedals from falling off. The model captures this effect using a multibody dynamics simulation together with a contact analysis. A friction coefficient is associated with the contact in order for the model to capture the effect. Read More
Solving very large pressure acoustics models in the frequency domain can be challenging. Several iterative solver suggestions exist for the default physics setups and the default quadratic Lagrange discretization. For very large models it can be advantageous to switch from quadratic to ... Read More
This model, dealing with the current and potential distribution around one pair of electrodes, demonstrates how to synchronize and modify geometry in PTC Pro/ENGINEER® by using the LiveLink™ interface. Read More
A waveguide filter is designed using shape optimization by moving and scaling rectangles in the geometry. The irises of the initial geometry are optimized to ensure good bandpass response and out-of-band rejection, while maintaining the double mirror symmetry. The EGO optimization solver ... Read More
This model demonstrates one way of using equation-based modeling for generative design by using the powerful mathematical expression capabilities of COMSOL Multiphysics®. Read More
This model is used to demonstrate the solution to a classic brainteaser in electromagnetics. A long loop of wire is connected to a source and a receiver, which are placed 1 meter apart. The objective of the model is to compute how long it takes for the receiver to sense when the source ... Read More
This example shows how to model the behavior of a thermostat where a delay in its reaction has been implemented. A more detailed description of the phenomenon, and the modeling process, can be seen in the blog post "How to Implement a Delay in Your Thermostat Simulation". Read More
This example shows how to create a time-limited and hardware-locked application. It is associated with the section "Time-Limited and Hardware-Locked Applications" in the Application Programming Guide Read More
In food industries, microwave heating is gaining attention over a conventional heating treatment because of several advantages such as precise process control, speed of heating, fast turn-on and turn-off time, etc. In this model, a high directional Yagi-Uda antenna is used to heat up ... Read More
