Hi, it seems that either you have clicked an option which requires additional input setting or you need to clear all solutions and re-run!
this type of error usually happened with me when ;
1. material properties have a zero , i usually changed it to a very small value instead
2. mesh , try to choose ur mesh carefully
3. ur solution step, try to change it
good luck
It may happened because of mesh type for your geometry,try other types of mesh.And give small values instead of zero for initial values.
