NVH Harmonic Acoustic Multiple RPM – frequency dependant mesh

      Hello,

      I need to create freqency dependent parametric mesh (air enclosure of electromotor) in order to reduce calculation time in Harmonic Acoustic analysis (low frequencies require bigger enclosure and not so small elements, while high frequencies does not requrie big enclosure but they require small elements).

      I am performing multiple RPM harmonic acoustic analysis in order to create waterfall diagram -

      Parameters are a powerful feature of Workbench, but only work on single step analyses. nMultistep analyses are a powerful feature of Workbench, but don't support Parameters.nMultistep with Parameters would be a superpower. Maybe one day...n

      Thanks for info.nIt means, only option to parametrize mesh the way i need (freq dependent), is through some APDL commands, but it would be too difficult i think for anyone. n
