I frequently encounter a problem when optimizing with the optically fabricated hologram (OFH) surface where the local optimizer or hammer optimizer will not close. I have to stop the OpticStudio process in the task manager and reopen the file. The hammer optimizer seems to be much more prone to this problem.

I will provide a toy file for examination shortly; however, I was wondering if this is a known bug or if there is a work around to prevent this behavior? I do call the HLGV operands and also the CMFV operands during optimization.

Hi Michael,

Sometimes it happens in long optimizations that a request to terminate takes time to process. This is known to us. All I can say now is that if you wait it should stop eventually. 

Thanks Kevin,

It must take a really long time. For the time being, I limit the number of cycles, i.e., avoid the infinite option and that avoids the issue. Automatic will also work if using the hammer optimizer.
