Induction heating using permanent magnets with conductive rotating plate Initially, I was trying to model the system using a combination of Magnetic Fields (mf) with permanent magnets (defined through remanent flux density), Heat Transfer in Solids, and Electromagnetic Heating coupling in COMSOL Multiphysics 6.0. For the rotational motion of the conductive plate, I attempted two different approaches: first, I used Moving Mesh (ALE) to physically rotate the geometry of the plate, and then I also tried Rotating Machinery Magnetic (RMM) to introduce the effect of motion in the electromagnetic equations. However, in both cases, the results were inconsistent: the plate did not heat up, and no Joule heating was generated. I also encountered an issue where the variable mf.Qh was undefined, which suggested that no electromagnetic losses were being properly computed. Because of these issues, I started reconsidering the physics setup and attempted to change the modeling approach.

Hello everyone i'm working on induction heating system using permanent magnets i had an error (initial values) can anyone help?

I'm working on induction heating system using permanent magnets to create eddy current i added rotation to the plate but it doesn't heat up any advice?

Hello everyone i'm trying to build my first pcb for a zvs using kicad how can i know that it will works before sending it to fabrication what' the most important things i should do to ensure good functioning

Hello everyone i'm working on induction heating system using permanent magnets i did the simulation using comsol multiphysics but there is problem the plate didn't heat up even it has rotation ( eddy current) can everyone here help? Is it a physics mistake?

Hello everyone i have issues with my simulation can anyone help? Leave a comment i'll give u details about the problem

I'm working on induction heating using permanent magnet i already draw the geometry and assigned physics to it but there is no heating my qst is how to assign rotation to the plate? Is rmm, heat transfer in solids and multiphysics sufficient for this study and what do you think the problem is?

Hello everyone I'm working on induction heating using a pancake coil I=15amps, f=200khz the temperature is about 500degc Now im thinking to change the study to stationary one but the piece will rotate Can u pls explain to me how to give rotation to an objet using comsol?

Can anyone tell how to choose transistors, diodes and resistors values for a ZVS?

Hello everyone i'm working on induction heating system using a pancake coil (i=10amps f=200khz) the temperature needed in the plate is 500degC i did a stationnary study! The plate heat up to around 520degC Now i wanted to change the study to frequency transient study! An error appears (solver out of memory) in the first case i calculate the inductance using comsol L=imag(V/I) =180nH but using a site of inductance calculation it appears 5.94uh? Why there is such a big difference? Is the type of the study has on impact on the results? And how can i fix the simulation study error! Any advice?

Can anyone here help me? I'm working with simscape electrical on a ZVS mazzilli pls if anyone can help i'll appreciate it i have to submit the work as soon as possible 🙏

Hi everyone i'm working on mazzilli driver simulation using simscape electrical i have some problems with it can anyone help?
