Default blunted cone-flare in hypersonic flow
Posts: n/a
HELLO I am a student of aerospace and i am intersted in CFD. I tryed to solve a hypersonic problem, i found a paperwhich solve somthing like that so I tryed to do like it, i meshed the flowfield but i got a high aspect ratio in some regions from 5 up to 400. please give me an e-mail address to send the pictures of my mesh. then i tryed to solve with fluent coupled implicit with a courant no. about .15 but it diverged after 13000 iterations.(not divergance but instable and the residuals are about 1e-5
