Hello fellow members,
I am trying to run simulations on tandem blades in Mises. I managed to get a decent grid from iset, but I am facing some troubles with while running ises. In short I would like to know the right combination of global variables and constraints for tandem blades (subsonic). I initially tried with (screenshot for list of global variables and constraints attached) : Variables: 1(inlet flow slope) 2(grid exit slope) 5(LEstagnation point) 15(Ma1) constraints: 1(drive inlet slope to Sinl) 4(trailing 15(drive Ma1 to Minl) This combination worked well for single element blade analysis. However it does not run for tandem blades. Precisely the error is "Convergence failed at...", "MIXOUT C-cell segment not found" Please find the attached image for the ises file used. I tried out some other combinations of global variables and constraints as well: '1 2 15 6 1 4 18 6' (this is similar to that used in the default tandem test cases provided by Mises:"arl2") '1 2 5 15 6 1 3 4 18 6' '1 2 15 16 1 4 15' And a few others, but none worked out. Also the tandem subsonic test case provided by Mises("arl2") does not converge either and displays the same error mentioned above. I hope that there are experienced Mises users in this forum who could help me out. With best Regards Legin Last edited by Legin; March 26, 2018 at 12:07. |
