# [ansys] simulation of permanent magnet in 3D

• s k gupta
In summary, the conversation is about a user, S K Gupta, who is requesting help with modeling and analyzing a permanent magnet in 3D. They are having trouble with the results and are seeking assistance in attaching the magnet's attributes to a volume in Ansys 15.0. They mention that they were able to solve the problem in 2D, but not 3D, and provide some details about the construction and desired analysis. Stevie suggests posting the question in a technical forum and provides links to the appropriate areas.

I''m facing problem in modelling and analyzing a permanent magnet in 3D. kindly help me out.

Sure, S K!

Post your query in one of the technical forums here at PF. There are several mathematics and physics forums which can host your thread, but please choose only one.

Try to include as much information about your problem as you can; certainly much more info than you have provided in the previous post will be needed.

The problem is to model a permanent magnet with a torus core .I just wanted to know how to attach attribute of magnet to a volume in ansys 15.0. I solved the problem in 2D but in 3D the results are not satisfactory and I'm not able to point out the mistake by me. the construction could be assumed to be a regular torus core with a section of permanent magnet with Hc 100000 A/m. Just a basic BSUM static analysis would be fine. I think this would be sufficient if not kindly reply .

## 1. What is ANSYS simulation and how does it work?

ANSYS simulation is a computer-aided engineering tool that allows scientists and engineers to simulate and analyze real-world scenarios in a virtual environment. It works by using mathematical models and algorithms to solve complex physical problems and provide insights into the behavior of a system.

## 2. What is the importance of simulating permanent magnets in 3D using ANSYS?
