Hi Michele,

Thanks for your question here!

A potential workaround to ignore ray trace errors for the universal plot is to define a Merit Function in which the  NSTR ray trace operand ignores errors. You can set this by enabling the “IgEr?” property.

You may find more information about the NSTR operand in the Help Files at The Optimize Tab (sequential ui mode) > Automatic Optimization Group > Merit Function Editor (automatic optimization group) > Optimization Operands by Category > Non-sequential Ray Tracing and Detector Operands

You may set the ignore error property either directly in the Merit Function Editor:

or in the Optimization Wizard as well when generating the Merit Function:

Then, you can modify your settings for the Universal Plot to call any operand performing analysis on that particular NSTR from the Merit Function itself:

I hope this helps, but if you have any further questions, please let us know and we will be happy to help!

Best,

Csilla
