  Hi,
  
  I am a beginner in Ansys Maxwell and trying to simulate a specimen, which is subjected to alternating current and I would like to know the potential drop (electric voltage) between to points.
  
  Does anyone have an idea how to get to this magnitude? Is there a known possibility to get the electric potential on a specific point or face in Ansys Maxwell?
  
  Best regards

  Calculate (ohmic) voltage drop along a conductive path
  
  Assume the existence of a conductive path (a previously defined open line (polyline) totally contained inside a conductor). To calculate the real and imaginary components of the ohmic voltage drop inside the conductor the following steps should be followed:
  
  For the real part of the voltage:
  
  Input > Quantity > J
  
  Vector > Matl > Conductivity > Divide OK
  
  General > Complex > Real
  
  Input > Geometry > Line > (select the applicable line) OK
  
  Vector > Tangent
  
  Scalar >
  
  Output > Eval
  
  For the imaginary part of the voltage:
  
  Input > Quantity > J
  
  Vector > Matl > Conductivity > Divide OK
  
  General > Complex > Imag
  
  Input > Geometry > Line > (select the applicable line) OK
  
  Vector > Tangent
  
  Scalar >
  
  Output > Eval

  Thank you for your support!
  
  I already tried this method to calculate the voltage drop along a conductive path. In my specific implementation there is an inhomogeneous electric field because of eddy current effects. I want to know the voltage drop from the bottom face of a cylinder to the top face of this cylinder and this inhomogeneous field makes it impossible to just calculate the voltage drop along a conductive path. Because every different path gives a different voltage drop. In my opinion I have to integrate over the whole volume of the cylinder and not just along one path.
  
  Therefore I tried to think of another possibility to get to the voltage drop and my suggestion was to find the electric potential on both of the faces and substract them from another. Do you have an idea how to get to the electric potential on a specific point of my model?
  
  Best regards!
