Asked 2nd May, 2020

How can I add alloying element to a material in Ansys Maxwell?

Hello,
I am trying to perform an electromagnetic simulation in Ansys Maxwell. In my case, I have a rectangular plate made up of Aluminium and I want to add small MnB (Manganese Boron) particles to this plate. For this reason, I have made a small sphere and assigned the necessary material properties. The small particles were placed inside the rectangular plate. But when I try to run the simulation I get an error message as: two parts intersect with each other. How do I add MnB to the rectangular plate made up of Aluminium? Is it even possible to do that in Ansys Maxwell?
Thanks in Advance.

Hello everyone,
I have been trying to simulate a 'simple' coil consisting of 4 connected springs with a thin circular (D=0.072mm) in Maxwell 3D. These four connected springs make a rectangle (top view) I have tried several attempts on modeling the coil in other CAD softwares and importing them into Ansys Electronics Desktop. Here is the list of attempts I made:
1- Modeling in Maxwell 3D and uniting the springs together to generate one single body - Result: current leaks to the air
2- Modeling in Solidworks and importing as .stp .stl .igs into EDT - Result: Cannot handle thin geometry (the coil will no longer have ciruclar geometry so cannot even apply a current to a terminal)
3- Modeling in NX and importing as .stp. .stl .igs into EDT - Same problem
Modeling one single spring and 2 of them connected to each other (attempt nr 1) did not give me error and 'Validation and Analyse all' was a success. But where I connected 3 or 4 of them, Ansys Electronic Desktop is giving me an error when 'Analyse all' is happening about current leak to the air which is not that straight forward to understand what's wrong, although the Validation goes well.
I also tried to model it in Design Modeler, it's interesting that first spring gets imported very well but the ones connected to it will have messed up geometry and at the end this one body geometry cannot be verified in Maxwell 3D (2 steps for simulation: Validation and Analyse all)
I would be extremely gladto be helped with this very problem and my main question is: does Ansys have hard time understanding and simulating such thin and fine geometry? is this the main reason? and eventually, what's the way out. I believe the main problem here is that I don't know what's exactly wrong. i.e. What does the current leak to the air mean? and where this current leak is taking place so I can modify my model. As a final comment, I tried both ways, open loop and closed loop.
Thanks, any comment is appreciated!
