nOne type of problem that is difficult to solve with Static Structural analysis that is easier to solve in Transient Structural (or Explicit Dynamics) is snap-through behavior. This occurs when a structure buckles into a new shape. It is difficult for the Static solver to increment the load gradually and remain in static equilibrium to get to the buckled state. But a Transient solver can solve the dynamic equilibrium by including the inertial forces that arise from accelerating the mass to snap-through to the buckled state.nSo the key difference is what type of equilibrium is the solver trying to converge on, static equilibrium or dynamic equilibrium.n
