Hello guys, i am a student and a beginner to CFD. I'm doing my final year project which related to wing in ground (WIG) craft especially in the prediction of lift force of the craft. I would like to ask any idea how to do the settings for my wing in hexpress? Thank you.

Hi romainRH, for your information, i am still working on my wig geometry. For the time being, i am trying to analyse the wing of the WIG. But, i have no idea how to do the settings. Here's the attachment of my meshed wing. Thank You.

Well do you want to modelised freeSurface? and/or a specific wind gradient? If not the main parameter Will be the viscous layer. But that is easy to setup in hexpress.
Are you working on only one half of the wing?
The exeternal domain seems to wide exect if you want do diffuse large pressure gradient.
Where is your trouble exactly?
