I see you have a barrel spring with a 20 mm wire diameter and about a 4 mm gap between the coils in the undeformed spring.
What do you mean by "overcoming" the gap?
Fix one end of the spring, compress the other end of the spring and Solve the Static Structural Model (with Large Deflection turned on). The gap will close and the coils will push against each other. That is one way to overcome the gap.
