ProteusDS 2013 Change Log

  • ProteusDS 2013

    June 4, 2014 (v.2.5.19)

    • Removed an unused UI element (Elapsed Time) in the simulation control panel in ProteusDS Simulation Toolbox.
    • Removed unintended access to a feature that is currently under development in PostPDS.

    June 4, 2014 (v.2.5.18)

    • Addressed an issue where an unnecessary window was regularly appearing in ProteusDS Simulation Toolbox when simulating.

    June 3, 2014 (v.2.5.17)

    • Addressed an issue where an incorrect fluid velocity could be applied to cable elements near the water line.
    • Addressed an issue where ProteusDS Simulation Toolbox, ProteusDS Queueing Manager, and ProteusDS failed to communicate in situations where a large number of warnings were generated.

    May 20, 2014 (v.2.5.16)

    • Added ExtCylinder feature to model cylinder extmasses on cables
    • HydrodynamicDatabase now requires a baseline buoyancy to be specified to balance out the weight force as multiple HydroDB can be used.
    • Added flags to enable/disable extra stiffness/damping
    • Added flags for enabling/disabling incident wave loads, diffraction wave loads, radiation wave loads, hydrostatic loads, and resistance loads individually
    • Added load scaling of HydroDB based on draft
    • Added simulation results file output of incident wave loads, diffraction wave loads, radiation loads, resistances loads, frequency dependent added mass/damping, and retardation functions. (Verbose mode only)
    • Added file output for CustomMesh hydrodynamic forces. (Verbose mode only)
    • Cable material properties can now be defined as starting sequentially from node 0 or node N
    • Added MooringOutput flag which will output simulation results that are only of interest for moorings such as the uplift angle
    • Added high frequency approximation capability for computation of retardation functions from frequency dependent damping function
    • Improved error checking and handling for ill-defined cable segments. Some cable segments may not be represented in the cable due to poor choice of element lengths. ProteusDS will now warn the user
    • Added WaveType 9 – Custom wave segments (deprecated $UseCustomWaveSegments property as a result)
    • Added additional right-click menu options in PST to assist with properties editing
    • Enhanced performance of I/O-bound simulations by reducing the number of related file operations performed

    March 27, 2014 (v.2.3.7)

    • Addressed a critical issue in PST that could lead to an unexpected program termination when saving certain types of project files

    March 24, 2014 (v2.3.6)

    • Modified layout of ribbon bar in PST
    • Added simulation control directly within PST (remove of running simulations via Console window)
    • Right-click “Go to feature” option added for easy navigation to feature entry in library
    • Added ‘Export Final State’ and ‘Save Copy As’ options for project creation
    • Added menu bar
    • Added default value when using intellisense to autocomplete; allow to revert to default value
    • Improved documentation for properties within PST
    • Added preliminary About Box.
    • Improved PQM, which allows for simultaneous monitoring of multiple simulations
    • Added Power Law current profile
    • Changed how foil feature external files are handled
    • ExtMass volume for buoyancy no longer removes volume of intersecting cable
    • Improved cable property documentation
    • Automatic peak shape parameter computation if not provided by the user
    • Helical joint for ABA
    • Extmasses are rigidly clamped to the cable to handle payout/payin. New extmasses can be spawned during payout.
    • Added Max curvature probe
    • Added min/max wave spectrum period limits
    • Added normal friction pressure coefficient
    • Added fluid diameter to DCable that allows for specification of fluid hydrodynamic loading diameter independent of buoyancy diameter
    • Added wave drift calculations to RB hydrodynamics mesh feature (experimental)
    • Diversified fluid coefficients feature for cable classes
    • Added grounded line length probe
    • Added rigidbody winch controller for manoeuvring position and tension control
    • Added probes to determine touch down point from either end of cable and corresponding grounded line length
    • Added uplift angle at each boundary of cable relative to flat bottom and local bathymetry
    • Added probe to print out legacy DNV pipe stress (experimental)
    • Added probes to determine minimum altitude along a span of a cable relative to local bathymetry
    • Added probes that are automatically created to print out minimum altitude of nodes that represent boundary of material property changes
    • Added current profile probe

    December 18, 2013 (v2.2.37)

    • Added new kinematic control modes for RigidBodies
    • Changed the ‘NumberOfThreads’ property in the ‘Integrator’ feature to classified as an ‘experimental’ feature to better represent its current status.
    • Added flags to several properties for PST to auto-display them, despite their ‘non-required’ status.
    • Addressed a number of performance and stability issues, particularly in relation to new features we hope to release in early 2014.

    November 8, 2013 (v2.2.35)

    • Addressed a number of visualization issues with waves in PostPDS
    • PostPDS will now use multiple threads to assist in rendering complex wave surfaces. This may cause performance issues on some older computers and can be disabled via the ‘Edit Water…’ dialog on the ‘Settings’ tab
    • A number of stability-related issues have been addressed
    • Added a number of new probes – check the manual for the full list
    • Added a number of new effects to cable DObjects – including thermal fluid stress/strain, hydrodynamic effects due to seabed proximity, and momentum flux loading

    August 8, 2013

    • Added RigidBodyTurbine feature
    • Updated Net DObject
    • Minor bug fixes
    • Improved localization support
