I know that ansys offers electromagnetic simulation, but can one coil electromagnetic radiation be induced on to a solid iron?
Physically it can be done of course. In simulation, there will have to be a combination of electromagnetic module and CFD. Electrified coil induces magnetic fields within the iron bar. The iron bar within the coil gets magnetised and then you get reactance. Magnetic field move from coil, via air, and then received by the iron bar. I will start work on this soon, preferably CFX. Any tips should help, thanks. |

I am no expert on the electromagnetics modelling capability of CFX so I am not sure.
But can I ask, why haven't you just read the documentation and tried it? Isn't the most obvious thing to do is to set up a electrical coil and iron core and see if it is modelled correctly? Wouldn't that be far quicker than posting it on the forum and waiting for an answer?

Thanks ghortocks
Yes, I was about to start, and now have done. I am following instructions, but still not clear. A new field for me. Basically a small disk magnet near a s small steel cylinder. When tried to solve, i got this error message. "Magnet, permanent, Ferrite Y30BH (YBM-2B) contains invalid property data." Still searching for away to fix this. Thanks |

Tried another example with just a silicon core iron magnet in air. Got this error message;
"Magnetic alloy silicon core iron, A contains invalid property data. These problems are: B-H curve is required, but is currently undefined." |

Got over the B-H curve. Just select a magnet material with a B-H curve.
The error message i have now; "An unknown error occurred during solution. Check the Solver Output on the Solution Information object for possible causes." |

Here is another attempt, using CFX. Please see attached image.
Basically an electric magnet coil as shown was assumed to magnetise the steel bar in the middle. Air flows across picking up heat. Any tips on settings, please? Thanks in advance. |

Here is another attempt, same error message. Settings seem to be correct, no errors. Please see attached file.

I think I got rid of above messages for now. Remodelled and reassigned conditions. Still I have another error message;
" the distributed ansys solution does not support solid117 elements ". Anyone please, and if these elements aren't acceptable, then why? Why did the software allow this to happen? |

solid117 elements suggests you are in ANSYS Mechanical, not CFX.
You should request an example from ANSYS support. Looks like you are wasting your time otherwise. If you don't have a support contract - well, this is why you pay for one ![]()

Thanks, but this is academic version. I will try to contact ANSYS.
Also, I am working on two magnetic examples. Using CFX and Magnetostatic. Different error message on two different problems. |

Dear Ghortocks
I am trying two methods, CFX and Magnetostatic tools. The Magnetostatic tool gave this error message; " Tree gauging for edge elements " " Gauge command aborted. " From my current knowledge, i need to select element 117. Or maybe some other way, just don't know how to get out of this. Thanks. |
