Surface vs FEM Loss Power Export Data - FEKO
I have a model consisting of 3 stacked copper windings over 10 feet in diameter with 15 turns (~15 ft tall). Each winding is approximately 3.00 inches wide, making this a fairly large structure. Positioned slightly above and off-center from the windings is a 3-foot-diameter torus (corona ring) with a 0.25-inch-thick plate…

Simlabの面重心への点作成について
Description:メッシュ作成の自動化を検討しています。 4気筒吸気系モデルに対して、入口面1か所および出口面4か所の面中心位置に点を作成するため、NodeByCentroid コマンドを使用しています。 解析対象となるSTEPデータは毎回形状が異なり、モデルを読み込むたびに面のUUID（または内部ID）が変化しているようです。 そのため、SimLabで記録したスクリプトを別のモデルに対して実行すると、前回指定した面を正しく認識できず、意図しない位置に点が作成されたり、処理に失敗したりします。 異なる形状のSTEPモデルに対しても、入口面および出口面を自動的に特定し、それぞれの面中心位置に点を作成する方法についてご教示ください。…

内部に中空パーツ（カテーテル）が存在する流体領域のテトラメッシュ作成手順について
Description: HyperMeshで流体のメッシュ作成について教えていただきたいです。 【作りたいモデルのイメージ】 太い管の中に、とても細い管（カテーテル）が入っているモデルを作っています。 中の細い管は「壁」として扱いたいため、細い管の中身にはメッシュを作らず、太い管と細い管の「すき間（流体が通る場所）」だけにテトラメッシュを敷き詰めたいです。 【困っていること】 テトラメッシュを作ろうとすると、以下のようになってしまいます。 1. メッシュを入れたくない細い管の中にもメッシュが作られてしまう。 2. 全体にメッシュを作ると、細い管がある場所も通り抜けてメッシュで埋まってしまい、細い管が壁（空洞）として認識されない。…

PSIM 시뮬레이션 오류 해결
다음과 같은 Boost converter 회로를 구현한 후 제어기를 달아 확인하기 위해 저항에 12/8.333 부분을 반부하 12/(8.333/2) 형식으로 update하였습니다. 하지만 이 과정에서 출력 전력이 원하는 100W → 50W 가는 것이 아닌 12W로 떨어지는 현상을 발견하였습니다. 해당 파형은 아래와 같습니다. 하지만 이러한 문제는 수식 형태가 아닌 상수의 형태로 실험을 진행하게 되면 문제가 없는 것으로 확인했고, 또한 open loop의 형태로 실험했을 때도 같은 문제가 있음을 확인했습니다. 혹시 이것이 PSIM 2026 시뮬레이션 자체의 문제인지 아니면…

SimLab Python script runs without error but doesn't update model parameters
I'm setting up a link between HyperStudy and SimLab to run a DOE. The goal is to vary the positions of components in the SimLab model and see how the responses change. The workflow runs, and HyperStudy writes parameters.xml correctly for each evaluation. However, the parameters in the SimLab simulation don't change, so…
