ACP tapered geometry fullfilling

      Hello everyone!

      I would like to make FSI analysis of AGARD wing. As some of you may already know it is full of one material composite wing like a wood. I'm trying to model it but I have some questions with the ACP. Is there any option or method to fill between to different cross section (at the tip and root of wing's cross sections) with lamination plies to make it full of that material? Please see the below figures:

      This is possible. The high-level steps are below. If you are new to ACP, then hopefully you can get some practice using the tool. let us know if you need more details
      Model wing as flat plate
      Create wood material and "fabric" in ACP, specify the fabric thickness to be the total thickness of the wing, wood may be orthotopic so you can specify that with orthotopic material properties or if you prefer isotropic material, then direction is not important.
      Create solid model
      Bring in the upper and lower airfoil cad geometry into ACP as a surface and use cut off geometry to the shape of the airfoil
      Alternatively, use thickness based on cad geometry, and import a solid that is the shape of the wing
      The cad geometry will need to be positioned properly wrt to the flat surface since ACP extrudes the flat surface in 1 direction to form the solid mesh, not 1/2 in each direction about the midsurface
      These last two techniques (one or other) will allow the solid mesh to conform to the airfoil shape.
      Please try this technique and circle back with questions.
