2.22.0.3514 (1030) Beta Release

Impermeable membranes

AquaSim beta 2.22.0.3514 introduces a series of changes to the impermeable properties for improved analysis and simplification.

See the information from our webinar on closed, flexible structures for information and backing papers.

Note regarding versioning

The main versioning of the AquaSim package follows the major.minor.patch convention, with an added build number at the end (ie 2.22.0.3514). However, the beta solver/analysis engine uses the created date (ie aqusim_2_22_1030) when in beta, and will be named the same as the main version when in full release.

After installation the install needs to be reactivate and the beta solver must be chosen from the activation screen, otherwise the last, official version will be selected.

Changelog 2.22 (30.10.2025)

Solver (1030):

  • Adjustments have been made to parameters related to impermeable nets
    • Definitions and adjustments of introduction of added mass, hydrodynamic damping, flexible tarp damping and factors for this (#2087)
    • Modification of factors for inner water mass (#2103)
    • Smoother in and out of water handling for drag loads and wave loads, impermeable systems that most often give better convergence (#2108)
    • Larger consistency also for 3-noded elements (#2085, #2082)
    • Possibility to include negative added mass and hydrodynamic damping (#2093)
    • Improvements of consistent mass matrix (added mass indicator)
  • Related adjustments have also been introduced to “Morison freeplate”
  • Adjustments made to Stokes waves to get them introduced to the analysis (#1964)
  • More options for winches, time varying velocity and stop if load gets above target (#2053)
  • The first wave is not applied linear anymore, but according to a polynomial meaning velocities and accelerations will be more smooth / continuous (#2108)
  • Possibility to introduce added mass in the longitudinal direction also for truss elements (#2110)
  • Slight modification of mass / added mass for the net itself for all membranes (#2083)
  • Adjustments to include the effect of added weight of nets if above waterline also for regular nets
  • Added writeouts to text files, reaction forces, hydrodynamic forces, beam and truss element forces
  • Improvements for NLD-table for anisotropic behaviour (#2106)

AquaEdit:

  • Winches can now have RAO to vary the speed
  • Renamed tangential drag to drag x (#2110)
  • Split Added mass and Drag loads on trusses
  • Added added mass coefficient for x direction (longitudinal) (#2110)
  • Pretension table for trusses can now be pasted into
  • Line elements are sorted by lowest node number when exported
  • Added negative mass choices for membranes (#2093)
  • The target X0 and Y0, and COSN used during generation for waves now visible in plot seastate (#2089)
  • Added option to enable Energy method (advanced) when exporting (#1803)
  • Stokes waves can now be chosen for environments

AquaView:

  • Changed water surface visualization to match new wave interpolation
  • The version the file was analysed with now shows in the bottom right corner
  • The colour of the stress values can now be set by user
  • Improved how information on springs are loaded
