Non linear solver does not converge, and simulation is very very slow

Simulation is very very slow also non linear solver convergence error. When i try to increase the time for simulation, then i often encounter "non linear solver does not converge" error. I modified some things in segregated solver but that is making simulation very very slow. How can i solve that problem.

Hello Jeff, I appreciate your points but I can't share the file on public platform. I can describe my problem as related to droplet impact. I am using physics as Solid mechanics, laminar flow, level set to track interface. also about 500k elements are being used to simulate this. I am using direct solver(PARDISO), and segregated solver, what are the best possible settings i can tweak in order to get convergence. Thanks
