When Analysing a structure using linear analysis, the results sound reasonable, however using P Delta Analysis, the software is giving me crazy results and instability problems for some loading combinations, Any suggestions ?
EDEM failed to load: CUDA Error nvcuda.dll This may mean that there is no NVIDlA driver installed on your system. EDEM could not detect a supported NVIDIA driver on the system. This may be because there is no NVIDlA driver installed or because the installed version is too old. Note that there is no need to install the CUDA…
Hello, I’m encountering an issue while trying to create the symmetry of my half fuselage. The model was built using a reference coordinate system. I then define a symmetry plane by selecting points on the open face of the fuselage. However, when I mirror the fuselage, the two surfaces do not merge properly and there is a…
Hello, When meshing a half model (fuselage + wing) using a symmetry plane, is it necessary to project a CCS curve onto the symmetry plane ? Thanks !
Hello, What are the main use cases and advantages of using OpenVSP before setting up a simulation in FlightStream ?
Hello, If a part of my geometry is meshed using external software, what key aspects should be carefully considered ? Thanks !
Hello, What is the recommended approach for meshing complex non-lifting geometries such as a rotor hub? Is the TFI mesher appropriate for this type of geometry? Or an external software ? Thanks !
Hello, What are the best practices for modeling the rotor hub–blade connection in transient simulations? Should a gap be introduced between the blades and the hub? Is it preferable to remove the hub entirely? Or should a gap be defined between the hub and the fixed geometry while allowing the hub to rotate? Thanks !
はじめに Radioss の接触 /INTER/TYPE7 と /INTER/TYPE25 には、摩擦エネルギを、熱エネルギに変換して、熱伝導解析の熱源とすることができます。 本記事では、簡単な例題を一つ示しながら、入力内容について説明していきます。 例題と説明 ダウンロード: 摩擦で熱が発生している様子。 本例題は、こちらの公式例題を元に作りました。 https://help.altair.com/hwsolvers/rad/topics/solvers/rad/thermal_analysis_example_r.htm この例題は、摩擦を熱には変えませんが、接触による熱伝達 (/INTER/TYPE7 内で設定) と、その熱伝導…
