Natural frequency extraction #676
-
|
Is it already possible to extract natural frequencies (eigensolver on bord?) and an analysis based on it (e.g. frequency response analysis)? |

I don't know whether or not the pre-compiled binaries support ARPACK, but in general the answer would be "yes". You can configure eigenvalue extraction by means of the "/EIG" keyword. See the corresponding documentation |

Great! I will try it tomorrow. Thank you for the answer. |

It is not possible to provide the direct usage of /EIG functionality in OpenRadioss, yet. |

It would be great if there will be a guide on how to compile ARPACK with the engine 😃 |

If it only requires compiling and linking to the appropriate versions of
OpenRadioss I am more than willing to give it a try. If it requires changes
in the underlying Fortran code, than it is more problematic for me.

Are there any updates on the natural frequency extraction with OpenRadioss? |
