Unable to apply Amperage in Steady State Electrical Conduction

  I am working on a research project, and I am currently trying to conduct an analysis simple geometry (rectangular block) to gather the necesscary boundary conditions I need to for my actual model. This is my first time using the electrical analysis system in Ansys workbench, and I am unable to apply current through my model without resulting in the error below. I haven't been able to find any tutorials or useful information online regarding this issue. I was able to get the simulation to converge, but I had to have an applied voltage and current in the "negative" direction. The research papers I am basing my boundary conditions on (for the acutal model) only mention inputting current for a certain period of time.
  
  A solver pivot warning or error has been detected in the VOLT degree of freedom of node 28 located in Solid. This is usually a result of an ill conditioned matrix possibly due to unreasonable material properties, an under constrained model, or contact related issues. Check results carefully. You may select the offending object and/or geometry via RMB on this warning in the Messages window.
