flapping wing help
hey...im doing a case study of flapping wing..first i took plate did hexa mesh in ICEM cfd..now in cfx i gave expression like
tan(10°)*(y-1.5[mm])*sin(2*3.15*3(s^-1)*t) dont mistKe me..i took this exp from a project..not working help me to give clear idea about flap exp and how to apply on cfx.. thank you |
What error message did you get? We cant help you otherwise...
I doubt CFX likes your degree sign (°) |
think so
actually error is negative volume element...due to mesh deformation..
when i increase the degree more than 10 error comes...also i neef one more help..i need exp for fixing plate on one side and moving on othrr side..like cantilever...i tried many exp not wotking..both mesh deformation and cantilever... |
Did you read this link: http://www.cfd-online.com/Forums/cfx...ease-read.html

* Negative elements are fixed by either remeshing or better mesh quality where it folds. Different mesh diffusion can also help * Prescribed mesh motion can depend on coordinates, and should be straight-forward to implement when you know the equation of motion. |
