SACS Static Analysis with PSI errors

Hi guys,

i'm getting started with SACS. I have to model a 4 legs jacket for wind turbine application.

I modelled in Precede (not using structure definition wizard) 4 legs above mudline, so i have 4 joints called 101L, 102L, 103L, 104L at base of the jacket. These joints are restrained with "pilehd" condition.

Now i want to attach 4 piles below the mudline connecting them to 4 legs by these 4 joints. I think i have to do this preparing a psi input file and then performing a static analysis with PSI.

Please, note that i haven't pile inside leg, i only want to have a connection between pile and leg at mudline.

In psiinp file i defined pile head joints (101L, 102L, etc.) and i assigned the correct properties.

When i perform analysis (with sacinp, seainp, psiinp files) i get these errors:

** ERROR - PILE DESCRIPTION AT LINE NO. 348
JOINT NUMBER 101L HAS ILLEGAL BOUNDARY CONDITIONS

** ERROR - PILE DESCRIPTION AT LINE NO. 348
NAMES PILE GROUP LABEL,PL1 ,NOT FOUND IN GROUP LIST

** ERROR - PILE DESCRIPTION AT LINE NO. 348
JOINT NUMBER 102L HAS ILLEGAL BOUNDARY CONDITIONS

** ERROR - PILE DESCRIPTION AT LINE NO. 348
NAMES PILE GROUP LABEL,PL1 ,NOT FOUND IN GROUP LIST

** ERROR - PILE DESCRIPTION AT LINE NO. 348
JOINT NUMBER 103L HAS ILLEGAL BOUNDARY CONDITIONS

** ERROR - PILE DESCRIPTION AT LINE NO. 348
NAMES PILE GROUP LABEL,PL1 ,NOT FOUND IN GROUP LIST

** ERROR - PILE DESCRIPTION AT LINE NO. 348
JOINT NUMBER 104L HAS ILLEGAL BOUNDARY CONDITIONS

** ERROR - PILE DESCRIPTION AT LINE NO. 348
NAMES PILE GROUP LABEL,PL1 ,NOT FOUND IN GROUP LIST

*** ERROR - NUMBER OF INPUT PILES 4 IS INCONSISTENT
WITH SACS STRUCTURAL DESCRIPTION,NO.PILES = 0

How can i solve these issues? I hope you can help me!

Thank you guys!
