How to I get the solver to correctly What You'll Learn: Setting Up Your Model: Step-by-step guidance on creating and configuring a transient mass transfer model in If you start solving a time-dependent problem with initial conditions that are inconsistent, or if you use boundary conditions or sources that switch instantaneously at a certain time, you induce In this blog post, we explore a simple transient heat transfer model and define different types of errors that can appear in a variety of We report on a combined experimental and computational module that can be incorporated into lecture or lab courses to enhance student learning about transient heat conduction/convection. Get the tutorial model Transient analyses provide the time domain response of a structure subjected to time-dependent loads. EDT Heat Transfer, Studies & Solvers, Physics We add a new, second, time-dependent study; solve for the conduction currents and displacement currents for the time-varying simulation; and show how to check our transient Hello, Is it possible to the transient simulation in COMSOL just by changing the source signal with different period? Without using the "Events" could we do transient? Due to the help of the angle-controlled cylinder positioning, with PEM e. To investigate the Microheaters used for gas sensing applications have been studied analytically and experimentally. Any suggestions why this happens and how to fix it? In this archived webinar, learn how to simulate turbulent flow in the COMSOL® software as well as how to choose the appropriate turbulence In this tutorial, we will use COMSOL Multiphysics to simulate transient conjugate heat transfer to analyze the cooling of a heated structural steel beam in the air. For problems involving diffusion, convection, and reactions which are by default solved using the BDF method with free time stepping, it is important to be aware of all of the following points. Includes Is it possible to simulate the application example structure given in here using a transient simulation? Basically to have an input laser, at the resonant wavelength, entering The COMSOL discussion forum covers a wide variety of simulation topics. Browse the threads and share your ideas with the COMSOL community. A transient analysis can be important when the time scale of the load is such that . stamping and extrusion dies can be machined. BDF and Generalized alpha are implicit I am solving a transient model which has loads that change instantaneously in time, but the solver appears to be missing some of these changes in the loads. Browse the threads and share your ideas with the Transient Modeling of a Coaxial Cable Application ID: 12349 Simulation of Maxwell’s equations in the time domain is useful if the objective of the What You'll Learn:Setting Up Your Model: Step-by-step guidance on creating and configuring a transient mass transfer model in COMSOL. Previously reported microheaters at The simulation speed is quite alright when it is solving transient state but as it enters the steady state the simulation becomes very slow. All of these, i In this COMSOL video tutorial, we explain how to perform a heat transfer analysis in COMSOL Multiphysics with radiation and convection boundary conditions. Learn how to set up and solve electromagnetic heating problems in COMSOL Multiphysics® that involve high-frequency loads. In this video, a time dependent (transient) 2-dimensional heat transfer problem is simulated. We explain how to set up the geometry Read this article to learn different approaches for solving transient model equations in COMSOL Multiphysics® when you have inconsistent initial There are three classes of methods available within COMSOL for solving DAEs: the BDF, Generalized alpha, and Runge-Kutta Methods. Boundary Conditions & In Transient ray heating simulation in COMSOL (Ray Tracing + Heat Transfer in Solids) Posted Aug 11, 2025, 6:58 a. The COMSOL discussion forum covers a wide variety of simulation topics. m. Learn how to model a generic wetted transient-time ultrasound flow meter using COMSOL Multiphysics® simulation software.
