Hi all! I hope someone can help me with this weird problem:
I am running a harmonic analysis with piezoelectric elements. In the post-processor I am reading the electric flux z-component for a number of nodes (all of which are corner nodes). I am interested in the amplitude of the electric flux. I try two different ways of getting the amplitude:
1. I read it out directly using: set,1,j,,ampl
2. I read the real and imaginary parts using: set,1,j,,real and set,1,j,,imag and then combine them mathematically (squareroot of sum of squares).
In both cases the actual readout of the electric flux is done by: *get,elec_flux,node,nodenumber,d,z. The weird part is that both methods yield exactly the same value (as expected) for about two thirds of the nodes that I probe. But for the other one third of the nodes the two methods are off by a factor of 3 to 42.
Has anyone ever experienced anything like that? What am I doing wrong?
Any advice is highly appreciated! Thank you!
