[Libmesh-users] computing lift and drag forces

[Bin L. <ken...@ho...>]

I am a new user and still not very familiar with libmesh library functionality. May I know how do I compute the drag and lift traction forces along a submerged solid wall in libmesh? Is there an example code for demonstration? Particularly, I need the nodal global coordinates, the shape function and shape function gradient values at the nodes along the boundary of  the solid wall.


Thank you
