I&#8217;m using the Electrostatic transient solver. My goal is to measure the electric field in the volume of tissue.<\/p>\n<p>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&#8217;t need the wire connecting them).<\/p>\n<p>I&#8217;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<p>Am I using the right Ansys package? Can I define the current excitation as a sine function in Ansys Maxwell 3D?
