Coplanar Waveguide - How to set up ports?
Hello community, I am currently working on a simulation involving a coplanar waveguide (CPW) in FEKO. The structure consists of a signal trace flanked by two ground planes. I’ve set up the geometry and boundary conditions, but I’m unsure if I’ve defined the ports correctly. There was an example online that I followed, but…

Why is the section plane moving in visualization mode (Post) ?
I have an issue related to the visualization of a CFD analysis. When I put a section plane and animate it, it moves, instead of showing the movement "inside" of it. Such as the current movement as the time passes. Before, when I was studying an individual piece it would let me, but now I have this big cluster of pieces and…

How to points globally in Inspire
Hi, I have a problem on my study case. I've a solver deck in Hypermesh and a model in Altair inspire. On that solver deck I have many holes for screw but on my model in altair inspire I haven't (they sent me the files like this), If it's possible, how can I tranfer my points from Hypermesh to Inspire? Alternatively I found…

Does Flux consider theese existing forces?
If I model an existing Lorentz forces based actuator in Flux I found out that the real forces seem to be less than the ones given by the simulation. I thougth that this could be because of some reasons and I do not know if this is already considered by the sowftware or not. This is the list of possible causes: -Brake…

SimLabの基板モデル化 トレースマッピング
SimLabは2024年前後から急激にECADの読込能力が向上しました。 ただ、例えば基板の熱のそりなどの問題では、微細な配線をそのままモデル化せず、ある程度大きな格子メッシュを作成し、そのメッシュ領域に含まれる各材料が占める体積の割合から加重平均により物性を計算するモデル化が良く使われております。 そのモデル化手法をトレースマッピングと呼ばせて頂いておりますが、SimLabでは非常に簡単な手順でモデルを作成することが可能です。 ご興味ございましたらご確認頂けますと幸いです。

Why does the holding plate move unexpectedly in CNTNLSUB, even with SPCs applied?
I have a transient nonlinear analysis in OptiStruct with two subcases to analyze (subcase 2 is a CNTNLSUB relative to subcase 1). In the first subcase, a holding plate engages with the rubber teeth to geometrically position them in their final location, having in consideration their final stress state (which is important…
