how apply the surface velocity of transducer as driving Answered
I got the surface velocity info of the ultrasound transducer by vibrometer in experiments then wanna apply it into the Onsacle model.(The following please see the part of code). I was wondering if I need to use the command piez defn to define the active electrode and ground electrode and the command piez conn to apply func at the active electrode.
hist drv1 5
func hist drv1
defn velocity vel func
node $i2 $i2 $j1 $j2 // the surface of ultrasound transducer or the active electrode of transducer
