#Comsol multiphysics 4.2 tutorial software

This application note focuses on a general capacitive sensor design that can be altered easily to fit any application. With this software, the sensor can be modeled for any type of application like touch sensing, water sensing and pressure sensing. It provides the user with the flexibility to model the sensor using a simple 2D user interface that can be easily transformed into a 3D model. Thinking about the problem, assume that we arrived at the followingĪpproximations (make sure you understand how we arrived at followingĪpproximations for your future quiz and test): The temperature of the heater isĬonstant at 400K.1 ECE 480 DESIGN TEAM 6 Designing a Capacitive Sensor using COMSOL Application Note Arslan Qaiser April 4 th, 2010 Executive Summary: Capacitive sensors can be virtually designed using a powerful 3D modeling software, COMSOL. We wish to determine the temperature distribution within the sheath. The entireĪssembly is immersed in a fluid and the system is at steady-state, as shown below. Thickness 0.05 m and which starts 0.05 m away from the center. The order isĪlso variable depending on the complexity of the model.Ĭonsider a cylindrical heating rod which is sheathed by a concentric tube of
