Electrochemistry Module Updates

Contact Resistance

The Electrochemistry Module introduces the ability to include external contact resistances in the Electric Ground, Electric Potential, and Electrode Current boundary conditions. This feature can be enabled by the Include contact resistance check box in the Settings window, and the desired resistance can also be specified in the text field.
