GGU-PLGW: "3D potentials (array)" menu item
The 3D effect is usually lost in an irregular triangular mesh. The "Evaluation/3D potentials (array)" menu item is useful here. After selecting the required parameter the following dialog box opens where you can define the array.

After leaving the dialog box by pressing "OK" you will at first see the same box as that described in "Evaluation/3D potentials". The program calculates the state variables at the array points by linear interpolation of the results of the FEM modelling. You then see the dialog box for coloured contours preferences as described in "Evaluation/3D potentials".
