I would like to simulate electrodes on skin in the Ansys Maxwell 3D package however I’m having trouble setting up an AC current source. I’m using the Electrostatic transient solver. My goal is to measure the electric field in the volume of tissue.<\/p>\n

I set up a solid representing some tissue and placed two electrodes on it (pictured). I would like to add a current source and sink excitation on the electrodes (I have since realized I don’t need the wire connecting them).<\/p>\n

I’m running into a problem where where Ansys says my current excitation is invalid without defining a voltage. I just want to use an AC current source because I need it to be constant across my experiments.<\/p>\n

Am I using the right Ansys package? Can I define the current excitation as a sine function in Ansys Maxwell 3D? How should I resolve that error?<\/p>\n

Thanks for your help!<\/p>\n
