How to extract two-dimensional(2D) electron/hole densities from Lumerical Charge

      Hi there

      In this model "https://optics.ansys.com/hc/en-us/articles/360042761893-GaAs-pin-diode",
      we can visualize the 2D electron/hole densities in the software.

      However, when I tried to extract the electron/hole densities data, "Charge-Visualize-charge-n-View Data", it presents a "3529 x 5" matrix, as attached Image1.

      In this matrix, it presents electron densities at 5 different voltages. For a particular voltage, it would be a matrix of "3529 x 1". We can not extract/plot the 2D electron densities with this "3529 x 1" matric, as it lost x,y information.

      Could you please help to extract the 2D electron densities data? Thank you very much.

      For each set of the 3529 data, you will need to interpolate the triangle mesh to reclinear mesh. Please refer this link  https://optics.ansys.com/hc/en-us/articles/360034405774-interptri-Script-command
