Autohydro Damage Stability Limits

Good day everyone,

I have a slight problem setting the limits in order to run Damage Stability in Autohydro. The strings that i was using untill now, had the following form

"Limit title MARPOL DAMAGE STABILITY
Limit (1) Abs Angle at Equil < 25
Limit (2) Angle from Equil to RAZERO OR FLD > 20
Limit (3) RA at Max > .1
Limit (4) Area from Equil to RAZERO OR FLD > .0175"

My problem is that i cannot set Limits (3) & (4) according to MARPOL Annex I reg.28.3.3. The required range in angles for Limits (3) & (4) is from equilibrium to "equilibrium +20deg".

Any help would be of assistance. Thanx in advance for any reply.

 

You can use it this way......

Limit title Marpol Annex I Reg 28
Limit (1) Abs angle at Equil < 25
Limit (2) Angle from Equil to RA0 > 20
Limit (3) RA at 20 > .1
Limit (4) area from equil to 20 > 0.0175

 

Dear athvas,

Thank you very muh for your reply. It worked for me and saved a lot of time cause instead i had to calculate manually. I was trying more complicated syntax and as a result autohydro would not "understand" it. The solution was much more simple.

Thanx again...
