How to visualize multiple reflections with ray paths in POSTFEKO with RL-GO and a plane wave source
Hi everyone, I'm working with FEKO using the RL-GO (Ray Launching Geometrical Optics) solver and a plane wave source (RCS problem). I would like to visualize the multiple reflections (ray paths) in POSTFEKO, but it seems that I can only see the first ray in the simulation. Is there a specific setting or output request I…

How to detect mesh intersections with Hypermesh version 2024.1 ?
I'm a FEKO user. I have a complex mesh (vehicle) with many mesh issues. A lot are from triangles intersections. But I cannot identify and correct easily. Can you help me by telling what are the actions within hypermesh to detect such triangles? I cannot find easily the solution within the trainings. Thank you.

Cantilever Beam
Hello, all, Please, I was wondering if it is possible to replicate the fixed end (circled in the picture below) of a cantilever beam in EDEM. If yes, how do I go about it? I will be using sphero-cylinders for the particle. I am trying to keep one end of the sherocylinder fixed and apply a load at the free end. Thank you

ビーム要素の自由度を開放する例題
はじめに Radioss はビーム要素プロパティで、要素の 1番節点と 2番節点の端の回転自由度を開放することができます。 両方のプロパティにこの ωDOF フラグがあります。 ヘルプにこのように開放 (さすがに誤記だと思います) とあるので開放という言葉を私も選びましたが、要素プロパティ、要は要素の計算に関する部分ですので、節点の自由度をうんぬんかんぬんするというよりも、その自由度に対する剛性を 0 にしていると考えれば良いかと思います。 本記事では、この機能を使って、回転の剛性をゼロにする例題を一つ示します。 例題 ダウンロード: このようなモデルです。普通のビーム要素なら、上につられて、下も回るはずですが、…
