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…

AutoSPC and RBE2
Hello, I have a model with solid mesh (tetras) with membrane elements at the surface. All are 2nd order. The part I am analyzing is attached by three bolts, which are modelled as RBE2. The SPC is applied to the master of these. When I run eigenmodes analysis I need the AUTPSPC function in order to get the correct…

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…

Level 2 IGBT model
Hi everyone, I’m trying to simulate a three-phase inverter. Using the ideal switch model, I managed to get plausible waveforms. However, when I replaced the ideal switches with the Level 2 model, the waveforms are no longer accurate. I’ve gone through all the videos and documentation I could find, but I still can’t figure…

45度の材料試験応力ひずみデータから、どのようにしてせん断応力とせん断ひずみの関係にしたらよいのでしょうか。
はじめに材料に異方性がある場合、0 度方向の特性なら、0度方向に揃えた材料の引張試験をして得られる、応力ーひずみの関係は、そのまま σ11 と ε11 の関係になります。 90度の場合も、90度方向に揃えた材料の引張試験をして得られた応力ーひずみの関係が、そのまま σ22ーε22 の関係になります。 しかし 45度の場合は、残念ながらそうなりません。45度に揃えた材料の引張試験を行って得られた応力ーひずみの関係は、単純に σ12-γ12 の関係になってくれません。 この部分ですが、あまり多くのコンテンツがなくて、必要なときになかなか出てこないと私自身感じていたので、本記事で、まとめとして記しておきます。…
