Velocity vector - incidence angle of aero profil - MotionView
Hi, I'm working on an aero project on MotionView. I need to return the incidence angle for a lift force calculation. The incidence angle is the angle between the Chord line of my aerodynamics profil (represented by one of the direction of a marker in my model) and the vector of his relative velocity, Vr. To calculate Vr, I…

How to simulate for a series of antenna.azimuth angles in api
Hello, I was trying to simulate with the api of WinPro. When it comes to define the antenna, I wonder if there is a way to input a vector so that multiple angles can be simulated at once. I noticed the variable WinPropAntenna.Azimuth is defined as a double and there's no exmple of it being a vector in the handbook. Thanks…

HyperMeshで3Dメッシュ作成する方法
いくつかの部品同士をブーリアン結合で結合したモデルにメッシュを作成していくとき、要素品質エラーで3Dメッシュが作成できないことがあります。 こういった場合、微小なエッジ部分が無くなるようにジオメトリを修正するのですが、ジオメトリを修正すると、すでに作成した部品の3Dメッシュが消えたり、どこかの結合が無くなってしまうことがあります。 ジオメトリを修正したら、もう一度すべてブーリアン結合をしてメッシュを一から作成するしか方法はありませんでしょうか？ 恐れ入りますが、ご教授ください。 よろしくお願い致します。
