right now there is no functor for that. But if your airfoil can be described by a function like here
you can create your own functor. It should be mainly copy-paste work, just have a look at
You can copy the IndicatorCircle2D, rename it and adapt the equation. Since there are probably more people interested in such simulations it would be great if would consider to send in your code for the airfoil-indicator and thus contribute to future releases of OpenLB.
