Hi，
I want to export fabric tensor in TXT.
>If i use fabTot=utils.fabricTensor(splitTensor=False) in plot.addData,
>resulting in an error.
ValueError: plot.addData given unhandled sequence type (is a tuple, must be
number or Vector2/Vector3/Matrix3)
>If i use fabTot=utils.fabricTensor(splitTensor=False)[0] in plot.addData,
>resulting in an error.
KeyError: 'f'
So,how can i save it in txt.
Thanks,
James
