GETPSF General Error

I have a macro calling GETPSF for various thicknesses to the focal plane, and I am getting np = -3,  'General Error' returned when I use Gaussian apodization.

I have checked that the FFT PSF is calcualting without error for the same thicknesses as are in my macro.

What else can cause a 'General Error' in response to a call to GETPSF?

A General Error is when the PSF cannot be computed by OpticStudio.

For example, when you get this error, it will return np=-3.

So would you mind sharing your examle with us? Feel free to open a case or send us an email at to share it.

Thank you!
