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
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..
What error message did you get? We cant help you otherwise...
I doubt CFX likes your degree sign (°)
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.
