ギアの応力解析（機構解析から構造解析への接触荷重マッピング）
Altairの機構解析ソフト「MotionSolve」と構造解析ソフト「OptiStruct」、さらに「MD-Tools」を組み合わせることで、ギアの応力解析を高精度に実施できます。MotionSolveによる剛体接触計算で算出された接触荷重をOptiStructへマッピングすることで、接触荷重を考慮した部品の応力解析が可能になります。これにより、ギアなどの接触部品の負荷条件をより正確に反映した解析が行え、設計の最適化や耐久性評価に貢献します。 本シミュレーションのチュートリアルを作成しましたのでご利用ください。 使用ソフト： マルチボディシステムシミュレーション| Altair MotionSolve 最適化が可能な構造解析ソルバー |…

How do I compute the current through a plane or along a surface in Feko?
Hello, I am trying to find a way to compute the total current through a small plane. Or alternatively to compute the current along a geometric object. For example, if I have a connecting element represented by a 1D-wire, I can read the current in the currents results. I am looking for a procedure that produces the same…

Is the Tab key no longer used?
I've recently upgraded to the 2024 version of HyperWorks from the 2022 edition. In previous versions of the "new" GUI, you could use the 'Tab' key to transfer from one selection field to the next. For example, in the split by surface tool you could select one surface and then click tab to move to the other surface…
