Default Factors restriction on RSM design

Hello,

There is a functionality of the software that is mentioned on the tutorial guide, and that I cannot find or apply :
what should I do to generate a Surface Response Design with restrictions applied to the combination of two factors?

For example:
I am trying to investigate the effect of the Delta Pressure (Pmax-Pmin) and of the Pmean ((Pmax-Pmion)/2), and I would like to generate a design that gives combination of DeltaPressure and Pmean so that
- Pmean – DeltaPressure/2 > 0 bar rel
- Pmean + DeltaPressure/2 < 5 bar rel

Do I have to do it manually by removing the unwanted combinations on Optimal Design?

Thanks for your help

Regards

Marco

Default Re: Factors restriction on RSM design

Unfortunately, DOE++ does not yet have optimal design with linear constraints. This functionality will be considered within a future release. Thank you for the suggestion.
