Dasom, Heo

I want to know the meaning of this code

https://support.onscale.com/hc/en-us/articles/360015568992-Pulse-Echo-2D

 

calc
disp 
pres aprs 
avrg pextr aprs * regn $i2+4 $i2+5 $j1 $j3-1 
avrg avrdsp ydsp * nod2 watr pmnpt
end

 

I understood meaning of those codes, but I didn't understand about the nodal range

in case of this code, I want to know $i2+4 $i2+5 $j1 $j3-1 

does it mean $i6 $i7 $j1 $j2?

Thanks.

    Hi Dasom,

    The keypoint i2 represents the nodal value at the location of the coordiante x2.

    For example i2 = 100 the next keypoint on this axis i3 = 150 the syntax i2+4 actually means 100+4 = 104 and so i2+5 = 105.

    Hope this helps.
