how can I get a converge at first step by using ANK solver?

Dear Researchers,
I am a beginer to use adflow. My case is a simple ellipsoid to flight at a condition of mach=0.03, altiude=20000m. I have tried to use ANK solver to start the calculation but it always print killed after startup. I believed it may be caused by convergence problems. Then I tried to use multigrid by tuning MGcycle to 5w. It can work but the process still be killed when it swich to ANK solver. After that I also use the explame files of wing_vol.cngs and bwb.cgns to try the same script. Wing_vol.cgns can be solved by ANK solver but bwb.cgns still shows the same problem that bing killed after startup. May I ask how could I check what problems cause this and what parameters can help to solve this?
Best wishes,
