How to export E-field to a custom grid?

[VigneshYork]

Hello,

I would like to export the E-field (overall field) to a custom grid. For example, I would like to compare the E-field in a plane perpendicular to antennas placed around the a femur before and after posing. Currently since the E-field can only be extracted according to the global coordinates, I am not able to extract the values I would like.

I would like to extract E-fields perpendicular to the antennas even when posed (the grid remains constant between static and posed models since it is relative to the antennas).

How do I proceed with this?

Thanks

The easiest way is probably to

• drag the antenna surface (where you want to obtain the perpendicular field) into the analysis explorer
• interpolate the field onto the surface (select the field and the surface, then choose the Interpolator tool)
• select normal projection (there is also tangential projection)
• visualize with a surface viewer

if the surface is too coarse, edit the faceting settings of the antenna, or remesh.

Hi,

Thank you. I tried it but would like to plot the fields on a grid between antennas (as shown in red in the image). It is easy when the model is static but when posed, I am not able to get a grid at an angle.

Thanks
