I am fairly new to Abaqus and would be happy for any advice. The problem: I have a round solid sandwich panel, which is situated between two shell elements. In the middle there is a Piezo-Active-Wave-Sensor (solid) placed on top of the upper shell. On top of the PWAS, a sine voltage is applied with a boundary condition and on the bottom 0V is applied. I now want to get the Frequency Impedance Spectrum for this specific problem. Therefore I tried to plot the RCHG value in order to achieve this. However, i get a bunch of errors when i run the job, although i have already added the RCHG (Reactive electrical nodal charge) to the "Edit Field Output"-Section inside the Step. Also something might be wrong with the tie, due to the warnings.
