Hi @arusu and @mchristiansen ,
I see that you are using the Premium Test Account which has only 200 free core hours (CH) usage, but has the possibility to maintain private projects. I can downgrade your account to free community account, in which case you get 3000 CH for carrying out the simulations. Please let me know if I can proceed with the same.
@mchristiansen The reason for not being able to select your "Aircraft blended winglet mesh" - could you please check if the mesh was successfully generated? If so it should be possible to select it to setup the simulation. In case you still have issues please send me a public link/project invite so that we could look into it.
