I am looking for more information regarding the error:

“Circuit solver failed, potentials were not updated. Stop the simulation if the problem persists.”

Could anyone tell me what could cause this or what they have done to fix it in the past? Should I look to time-step sizing or mesh quality issues first? Implicit/explicit circuit solver does not make any difference here it seems.

Thank you,  
Tyler
