Hello Luke,
I believe that this question is probably more appropriate to QTCAD than to RESCU.
Unfortunately, it is currently not possible to predict the stray fields of a micromagnet in the currently available QTCAD version as this would require a magnetostatic solver that we do not have yet. However, we may consider adding this feature to the package given sufficient customer demand.
However, for a given stray field, defined by the user as an arbitrary function of x, y, and z coordinates, it is possible to calculate the Zeeman effect even if the field is inhomogeneous.
I hope this helps. We would be glad to learn more about your context and what you would like to do with QTCAD, beyond simulating micromagnet stray fields.
Best regards,
Félix
