Dear Professor Gibson, 

Thank you for what you have done for us. 

There a DNS Algorithm PPEQ in older version, for examples, version channelflow-1.0.0, but it is tossed out in the newer version. Can you let me know if the Algorithm PPEQ is right? 

Thank you for help. I am looking forward to hearing from you soon. 

Best regards,
