Triaxial accelerometers, response axis selection

[edubueno91]

Hello,

I am trying to conduct a modal analysis with triaxial accelerometers w/out changing any cabling in the process. I have defined a NIMAX task with 3 accelerometers and with the accelerometers connected according to the local coordinate system of the response node (ch0-x, ch1-y and ch2-z). Nevertheless when I try to carry out the measurements there is no way to define what accelerometer we want to use as response for the recording and estimators. By default the ch0 is selected (see second screenshot below) and I don’t see any option to change it. Could you help me?

Maybe it could be easily changed in the source code. @matmr can comment on that.

Thank you for the response @miha-pirnat So for the moment, for a roving hammer analysis, the best option would be to carry out the excitation for all the reference nodes for one accelerometer and then physically change the orientation of that accelerometer and repeat until the 3 axis are captured for all the excitation points, don't you think?

yes, i think that is the best option.
