Issue with disallowed combinations filters in DOE

[#1]

Dear Community,

I have two factors for which I want disallowed combination i a Custom DOE.

If the "Accel step 2 = 0  , there can't be any "speed from step 1"

if the Accel step 2 > 0, there cannot be any "speed from step 1" at 0.

I tried to translate like this :

Accel step 2 == 0 & Relative speed from step 1 > 0

| Accel step 2 > 0 &Relative speed from step 1 == 0

The DOE generated is indeed removing these two conditions but also removing other conditions that I need in the DOE, like : 

Accel step 2 = 0 and speed from step 1 >0

what is the reason of it and what could I do to solve it ?

Thank you so much for your support.

Hello @Alex83,

Welcome in the Community !

Without more details about the factors type, ranges, any constraints you may have between other factors, assumed model, etc..., it's hard to help you. Can you provide your design table so that we can use the same factors settings and see what doesn't work ?

Best,

Dear Victor, 

Thank you for your feedback and your support !

Here is my config : 

factors are continuous and start from zero.

These factor are not independent:  if acceleration is zero, the speed cannot be bigger than zero. 

same if the speed is bigger than 0, acceleration cannot be bigger than 0.

However, acceleration and speed can be both 0.

I have put the DOE enclosed.

Best Regards,

Alex
