Dear SACS users,
I got a warning during analysis which are:
*** WARNING: REDESIGN STOPS FOR INVALID GEOMETRY - BETA - OF COMMON JOINT 1138 - CHORD JOINT 1139 - BRACE JOINT 940
*** WARNING Theta(Deg) VALUE OF 29.99 IS OUT OF VALIDITY RANGE FOR…
Hi,
I would like to perform time history fatigue analysis. Is there any sample or procedure on how to perform the analysis in SACS? in case yes, please feel free to send it to my email. ( ali_aidibi_94@hotmail.com )
Many thanks in advance.
Best…
Dear all,
kindly please your advice and enlighten regarding this issue. I tried to run Static Analysis in SACS consists of Gravity Loads, Environmental Loads, and Inertia Loads on FPSO Module.
unfortunately, I found some strange results for the…
Hi Geoff,
I just did a static run for topside module with dummy members to account stool stiffness and introduced joint fixity of 222000 on primary joints. However, the analysis stop due to error on illegal joints everywhere.

Hi,
I would like to know if there is a failure pattern called "Domino failure" in Push Over Analysis from which we can identify which member/joint failed first and then failures of member/joint connected to first member/joint in sequence ?
Dear All,
I am trying to model a beam resting over another. I have couple of option i can utilize but not certain which will be more realistic and recommended
1. Provide offset to raise beam to rest over other.
2. Provide new point over in Z- direction…
Is there any limitations regarding OD/Length ratio for the PSI convergence?
I'm experiencing a problem and cannot figure why for the exactly same soil data, with 25m of length, a OD = 3851mm pile converges and the other with OD = 5000 mm does not…
Dear Sir or Madam,
I would like to ask some problem that I encounter when I use SACS 5.7
I am performing Ship I mpact analysis (Static) on a wellhead fixed platform based on the practice workbook provided by Bentley.
When I start running the analysis…
Hello friends,
I'm an internship in a Offshore Oil and Gas service and supply company and I started working with SACS recently. I have a question concerning fatigue analysis:
What are the steps to follows to do a time history fatigue analysis knowing…
I found there is an push pull force at the base with master slave in staad.
But in sacs I am not getting the push pull force for the same configuration.
It is in one of the settings in Analysis Options. In my case, the utilizations in beams are changed drastically when I change the option from ON to OFF or vice versa. Which is the correct setting to use?
I have A special Case.- A Jacket being towed into position.I Used Floatation to arrive at the Bouyancy requirements but I am not sure how to check the Tow resistance and sling forces if the Jacket is to be towed into position.Can anyone help me how to…
Dear sir, I’m new student who is learn about flotation and upending analysis using SACS from Bentley. In my analysis, I got too much error when using this software. The bottom of jacket always touches the mudline when the hook elevate upward. When I decrease…
Dear all experts,
I have practiced to use SACS Marine Enterprise and I run "Upright Hydrostatics" of pontoon barge which comprises topside, jacket, and the other object. Cargo is an SACS model file that import to stability. Then, it is located on the…
Hi everybody, I still don´t get any response to this request, I believe that the answers do not come on this forum soon, I hope to receive a reply from you soon...I´m ten days waiting a response. Thanks.

In the detailed results of a segmented Member, SACS indicates that the overall buckling length for segmented members is recalculated according to the buckling load of that segment. Can anyone show me a solved manually example, showing the way in which…
Hi.
I have been trying to make a fatigue analysis and I have some problems with the results of the analysis. First, when I make the dynamic analysis to extract modes and shapes, the result gives me a warning of no unity check option selected. what does…
