Solving X resonant modes with identical natural frequencies gives unexpected results - why?

Solving X resonant modes with identical natural frequencies gives unexpected results - why?
The case of a model with exactly identical natural frequencies is causing the "x resonant modes around center frequency" routine to get confused. A few things that can be done: read more

Can I set the angle for a DAF applied on an SEA panel?

Can I set the angle for a DAF applied on an SEA panel?
The angle can be set for an NCT, so a workaround is to use a "gap" NCT and set the angle for this NCT read more

Why would one want to use the Efimtsov model instead of the Cockburn/Robertson model for a TBL source?

Why would one want to use the Efimtsov model instead of the Cockburn/Robertson model for a TBL source?
From Graham: the main advantage of the Efimtsov versus the Cockburn/Robertson model is that it accounts for the dependence of the decay coefficients (i.e. correlation length) on boundary layer thickness. read more

Does VA One SEA use cached data when solving in batch mode?

Does VA One SEA use cached data when solving in batch mode?
Does VA One SEA use cached data when solving in batch mode?, Yes, with a .va1 as input to the batch solve, VA One SEA will use the CLF's cached in that .va1 if they exist. read more
