SubscriberHi,
I'm using Maxwell 3D, the 2024R1 version for these simulations. And my solution type is AC Conduction.
I'm trying to model a muscle signal and record the voltage from the surface of the model. In my model I have 5 different materials for various human tissues with varying dielectric properties for each (cancellous bone, cortical bone, muscle, fat, skin). I have adjusted the thresholds so the perfect insulator boundary is below each of the values for these tissues since they have low conductivity.Â
When I run my simulation, I get a curve with the correct shape for normalized voltage around the idealized model, but I expect the values to change from basically 0 to 1, but instead I get values from about 0.8 to 1. I suspect my error is with the set up of the material properties? But it is possible there is something else I'm overlooking. Attached below are the some images to help show the problem. Any help would be appreciated!

Figure 1: Normalized Voltage plot I get that I would expect to range from 0-1 with this same shape.Â
Figure 2: Plotted Voltage Field on surface end where voltage excitation is applied. The gradiant seems fine, but I would expect the dark blue areas to be zero or close to it.Â

Ansys EmployeeHello Amber,
   Do you have 0 voltage in excitation? I agreed that the perfect insulator boundary is below each of the values for these tissues since they have low conductivity. You may need to have 0 voltage if some objects have 0 Volt.
