Importing .stl file Issues

    • EdK

      I'm trying to import a .stl file to define a structure in Lumerical FDTD. This does not work as when I import the file nothing appears, I can see that in the object tree the object is there, but in the view box there is nothing there.


      Varying the scale factor does not seem to work. I used the example .stl file from https://optics.ansys.com/hc/en-us/articles/360034901953-STL-import-Simulation-object. This one works fine, so I suspect it is an issue with my .stl file. It works fine in COMSOL, but Lumerical seems to have issues with it.

      Can't find a way to upload the .stl file to this post, but I have attached an image of what the .stl file should look like. 

      Kind regards,

      It might be version issue. What stl version you are using?

      did you try those:



      If problem still exists, please send us your stl file together with your solidwork version and software version to the support email.

      Later please write your post here https://forum.ansys.com/forums/forum/discuss-simulation/photonics/  for photonics software (Lumerical).
