How to plot the partial derivative of Magnetic flux

Please login with a confirmed email address before reporting spam


From the Magnetic field simulation result, I want to calculate the partial derivative of magnetic flux density.

Though, magnetic flux density shows fairly good result, the derivative of magnetic flux density is trivial.

That is, I want to calculate pd(mef.Bx,x) from mef.Bx, mef.Bx is 0.

Based on the exising technical forum, I chaned the discretization option, there was no difference.

Could you let me know how to sovle the partial derivative of magnetic flux density, pd(mef.Bx,x), by change any option in the model?

Thanks,

I think you should be using the d(...) operator to get what you want, not pd(...).

Thank you for your reply.
However, it doesn't work to apply d(...) instead of pd(...).
