SACS Readme

Details of Program Enhancements and Corrections

Collapse Advanced

  • Defect: A crash has been fixed when a pile-soil super-element is input for Collapse Advanced analysis.

  • Enhancement: Collapse Advanced now models the member end-releases using a special element to include large deformation of released degrees of freedom. For formulation details see Section 6.8 in Collapse Advanced User Manual.

  • Enhancement: Added Sample 24. This sample contains many examples showing the collapse advanced capabilities.

Collapse View

  • Enhancement: CollapseView now reads the SACS model input file alongside of Collapse Restart file.

  • Enhancement: Added ability to generate SACS input file with deformed structures for a given load step

Dynamic Response

  • Defect: When choosing the Velocity check option in dynamic response, the values are all zero in chartvue. The issue is fixed to transfer all the values correctly to chartvue. Also Listing file units for velocity checks are now fixed.

  • Defect: Fixed units for BS and OTM for periodic vibration analysis.

Dynamic Super Element

  • Enhancement: Transient Reduction is added to omit initial transient time for Dynamic Super-element outputs.

  • Defect: Fixed a typo in the Wave Load units in additional CSV files.

  • Enhancement: Dynamic Super-element program now generated outputs in four formats:

    • Siemens BhawC (default)

    • GH Bladed

    • MHI Vestas Flex 5

    • SACS FAST

  • Enhancement: More analysis details are added to the Dynamic Super-element listing file.

  • Enhancement: Warning and error messages are revised for clarity.

  • Enhancement: The wave elevation is added to Dynamic Super-element outputs.

  • Defect: Fixed crash when number of wave load steps are very large.

Dynpac

  • Enhancement: Dynpac is updated to handle footprint loads points as many as required. The 600 limit has been removed.

  • Defect: Dynpac now prevents Footprint duplicate weight at member ends.

Fatigue

  • Enhancement: Added option to read damage files from a particular range. Applicable to wind turbine process only.

Interactive Fatigue

  • Defect: Re-enabled choice of Load for fatigue reports and plots launched from context menus.

Joint Mesh Utility

  • Defect: Fixed Problem finding the intersection of an intersection curve and another member when the intersection is near the start or end of the intersection curve.

  • Defect: Member section line was not being included when meshing ring. 

Precede

  • Defect: Fixed bracing tubulars do not export correctly on update to ISM repository.

  • Defect: Fixed UC label in Precede does not match UC in listing file when using the JO option.

  • Defect: Fixed Bending moment diagram for beam with concentrated moment load is incorrect

  • Defect: Fixed printing issue when “Printing all views in Selected Bin” to PDF.

  • Defect: Fixed issue storing more than 30 views.

PSI (Pile/Structure Interaction)

  • Enhancement: Add soil liquefaction commentary to PSI manual detailing the equations and methods used.

Seastate

  • Enhancement: Added the ability to output a corroded model.  New member groups, sections, and plate groups will be created for members and plates that are corroded.

  • Defect: Seastate was updated to write out more significate digits to the OCI file on the MEMB line for density and effective OD when running a DYPAC analysis.

  • Defect: Fixed crash when using PGRUP2 line

Wave Response

  • Defect: Fixed crash when more than 20 dummy nodes were kept.

  • Enhancement: Added option to include radiation damping for monopiles.

  • Enhancement: Added option to skip initial transient time in time history analysis in WAVTIM line.

  • Enhancement: Added option to enter seed for wind spectrum.

  • Enhancement: Added option to enter five-digit seeds for wave spectrum.

  • Enhancement: Added option to skip initial transient time in time history analysis in THIST line.
