Multi-Static Kinematic Model of Magnets Error

Hello

 

I am new to Altair Flux and I am trying to plot a torque-deflection curve for the following permanent disc magnet arrangement:

 

(Note: Infinite box is hidden)

Where:

-The two magnets inside the yellow boxes rotate about the centreline shown in the LHS screenshot above

-The yellow boxes are the mobile air regions that the two magnets move through

-The four magnets outside of these regions are fixed and interact with the rotating ones to generate a torque

 

I have used the rotating motion tutorial shown below to help set this simulation up (adjusting it as best as I can for the model differences):

I followed this as closely as I could when I set up my model

 

When I try to solve the simulation, I get the following error:

(Note: For each line that reference geometrical features, I have highlighted them in the model on the RHS)

For the faces referenced below:

- Nothing on the model is highlighted when I select them

- I cannot delete them because of their usages

- They are all used with lots of features (FaceElements, Nodes, Triantops, a few volumes), which is confusing as I cannot see them on the model or infinite box

 

This is most of the advanced error info:

From looking at the information provided, does anyone know what I could be doing wrong to cause these errors?

I can provide additional information if required

 

Thank you in Advance

 

Rory
