<p>Hello GMSH Team: Fahad here</p>
<p>
<br></p>
<p>I have built a wind-turbine blade in GMSH using following steps:</p>
<p>1. Point coordinates of airfoils distributed along span</p>
<p>2. Connecting points using splines to first make airfoils</p>
<p>3. Then connecting airfoils through splines running through
points along airfoil surfaces</p>
<p>I have two questions:</p>
<p>Question 1) how can I make this blade a solid? I only want the surface of the blade as a plane or ruled surface and not the individual airfoils. Please suggest how can I create a solid and a volume in my case?</p><p>Question 2) I rotate and duplicate this blade to generate a rotor of two blades. Original blade has 259 lines and now after rotation with duplication, I should have 518 lines but I get 480 lines only as shown by statistics and also by hovering over the splines I see that tags are missing. Kindly help. </p><p>Thanks</p><p><br></p><p>Thanks. </p>
