    No Penetration SOL103

    I've attempted to use a CGAP element but the SOL101 does not like it. I think this element is non-linear only!!! I've tried to use "surface-to-surface contact" it seems to work, but I still have some fea elements that penetrate each other!!! It might have to do with the settings of the...

    B&K Pulse PL Functions

    Apologies for the delay. You are right Greg. The result Should be very similar to one of the signals but "enhanced", I think! And with a "relative" phase angle between the reference and the signal. I need these measurements "live". It is the bases of InvBEM. Which calculates the "Inverse...

    B&K Pulse PL Functions

    Does any one know how to do the following PL function in B&K Pulse PL language: Result = CPSD / sqrt (PSD) Where: CPSD is the Cross-Power Spectral Density of two signals x & y PSD is the Power Spectral Density of one of the signals sqrt is the Square Root. Cheer.
