Net electric force on a part

[mikebscott]

I am modelling a MEMS comb drive, and was looking to find the net electric force on one of the combs.  I made a simple model, as my model was too large to attach (even after compression, archiving, and zipping).  In this model, I am looking to find the net electric force (magnitude and direction) on the part named "Oscillator Comb".  Is there a method to do this?

Thanks for your help,

Mike

Model is attached, in a zip folder.

Hi Mike,

It's very easy! In the Results environment, you want to display "Results Contours > Electrostatic Force > Vector Plot".

Then select the nodes where you want to sum the forces, right-click, "Inquire Results".

On the dialog, set the summary drop-down to "Sum", and the adjacent field will show the sum of each vector component.
