AMG solver Divergence HELP please
 

Hi everybody
im doing my thesis and i need to simulate a clarky profile (2d ddp steady)
mi mesh is a gambit c-mesh (max screw 0.18) im using pressure far field BC and pressure outlet, i cant get convergence when i use pseudo-transient option it dramatically diverge, can i attach my journal and my mesh? anybody could check them? im really going crazy but i cannot figure out why it doesnt work

mesh file was too big if some one give me his e mail i can send it.
So sorry for teasing you but i really need help
