Vesta is on a distinguished road
Hello all,


I am currently working on a simulation to study the aeroacoustics of an airfoil using a NACA0012 airfoil as an example. Currently I am still at the meshing stage and have already tried a few possibilities. Parts-based meshing has so far delivered quite good results in the steady-state observation, but also required a lot of cells (8.5 M). Now I have created a mesh with the direct meshing function and that looks quite good for now, but I can't think of a way to improve it. I would like to have a finer mesh behind the airfoil to resolve frequencies of 2500 Hz and to decrease the skewness in general (see pictures).

Do you have an idea how or if I can realize this with the driect mesh option?


Thanks a lot!


Greetings
Vesta
