Extracting nodal positions in user defined coordinate systems

    • amit.pandey


      I am trying to extract the deformation of a lens surface with respect to user defined coordinate systems as seen the image.

      I would like to extract the positions of the nodes in these coordinate systems before and after deformation so that I can remodel the surface after the deformation by extracting the .txt file and processing it in MATLAB. The end goal is to generate the deformed surface that can be used in an optical simulation software to compare the lens surface before and after it deforms.

      You can add a user defined result with expression LOCX/LOCY/LOCZ (un-deformed coordinates) and LOC_DEFX/LOC_DEFY/LOC_DEFZ (deformed coordinates) - scope it to the user defined coordinate system and export it to a .txt file.
      Regards Ishan.
