Ansoft Maxwell virtual vs Lorentz force

[gatopardos]

Hello people, I am trying to model a motor in maxwell that has an array of magnets in it , the thing is that I get the non zero forces for the magnets even when there are no excitations if I choose virtual forces , I am selecting the whole array of magnets so the computation should be for the center of mass of the magnet array , I get the correct zero force when I use lorrentz force in magnetostatic solution but if I choose transient analysis only the virtual forces can be chosen and then I get fictitious forces, is this a bug of maxwell or does it have to do with the way the virtual force is computated? What is the difference between virtual and lorentz force in maxwell?

The difference between virtual and Lorentz forces in Maxwell is that the Lorentz force is a physical force that acts on the model due to its interaction with a magnetic field, whereas the virtual force is an artificial force that is used to represent the effect of forces such as gravity or friction. In your case, it sounds like the virtual force is giving you an incorrect result and there may be a bug in Maxwell. You should contact the Maxwell support team for help in troubleshooting this issue.
