Why does PO-LE appear to get less accurate as iterations increase?
A monopole antenna on the helicopter should have about 5-6 dBi of farfield gain. When using PO-LE (coupled with MoM) and limiting it to 1 iteration, it shows about 5-6 dBi of gain. However, as the iterations increase, so does the gain, until ulimited iterations gives >23 dBi of gain! What am I doing wrong? Does PO-LE only…

Is it possible to automate the export of HypermeshData from EDEM?
Hi, I would like to evaluate data from EDEM in HyperMesh. Since my calculations run on a cluster and I wanted to save myself the trouble of downloading all the data first, I wanted to know if it is possible to automatically write the force data at the individual nodes as csv while the simulation is running, or to export…

MotionSolveでシミュレーションした後，EDEM連成でContact設定をそのまま引き継げますか？
現在、アルミ製の粒状ダンパを自由落下させるシミュレーションを行っています。 マニュアルに従って Contact 設定をしていますが、まず容器がゴム床に衝突し、その直後に内部の圧縮版が容器下部に接触するためか、応答が安定しません。特に、地面との 2回目の接触時に構造全体が転倒してしまうような挙動を示します。 私としては、まず MotionSolve 単体（粒子を充填していない状態）**で粒状ダンパを自由落下させ、現実的な挙動を再現できるようにしたいと考えています。その後、EDEM 連成で粒子を追加しても、同じ Contact 設定でシミュレーションを続けてよいかをご教示ください。…

Total support reaction moment
I have a simply supported model in SimSolid with four supports. Each reaction support has a reaction in only the Z direction (or essentially zero in the other two axes), and zero moment reported. However, when I select all of them in the dialog box to get a total, the resultant moment is quite large in the X & Y direction,…

音響メッシュだけでの固有値解析
はじめに OptiStruct のヘルプには様々な例題があるのですが、シンプルに、音響メッシュだけで、音場の、固有周波数 (共鳴の周波数) を計算するものがありません。なにかと、構造―音場連成の周波数応答解析のようになっていたりします。 そういったモデルも、構造の振動解析モデルと、音場の振動解析モデルの組み合わせですので、音場だけの固有値解析モデルの作り方を知っている方が、何かと、そういったモデルを理解する助けにもなると思います。 そこで、本記事では、非常に検証が簡単な、両端を開放した管が作る音場の固有周波数を求めるモデルを提示します。 モデル ダウンロード: 長さ 220mm, 直径 10mm…

panopticon 슬라이더 및 다중 인풋 입력 문제 보고
안녕하세요, 몇달 전 판옵티콘 대시보드에 대해 문의드린 적이 있습니다 이후 2025.0.1과 최근 업데이트된 2025.1.1 로 업데이트 후 재시도하였으나 1,2번 문제는 여전히 지속되고 있습니다 1) 대시보드에 액션 슬라이더와 액션 텍스트 박스를 같이 넣었을 때, 텍스트 박스에 직접 숫자를 입력하는 방식은 결과출력에 전혀 문제가 없습니다. 하지만 슬라이더 사용시, 아웃풋 항목들이 간헐적으로 사라지는 경우가 발생됩니다. 동시에 액션 텍스트 박스 값이 슬라이더 이동에 따라 변경되는데 이 값에 소수점이 굉장히 많이 표시됩니다. 이게 원인인지는 모르겠지만 사용자 경험면에서도 좋지…
