The class of programs called “panel codes” solves simplified fluid and aerodynamic problems such as flow around boats and appendages, and predicts lift and drag over wings. These codes can be used to explore the interactions between adjacent vessels submerged or floating in water.

ANSYS AQWA:

MMC engineers are experienced users of the ANSYS AQWA three-dimensional linear diffraction/radiation panel code. Used for fast, efficient simulation and analysis of single or multi-body marine structures, AQWA solves the coupled diffraction problems in six degrees of freedom. The program includes Morison elements that can be used to analyze and simulate complex mooring systems and riser systems. ANSYS AQWA software addresses the vast majority of analysis requirements associated with hydrodynamic assessment of all types of offshore and marine structures, including:

  • SPARs
  • Ships
  • FPSOs
  • Renewable energy devices
  • Semi-submersibles
  • Breakwaters
  • Tension leg platforms

MMC has extended the capabilities of AQWA by the use of an extensive set of user defined functions and scripts, and we have incorporated AQWA into larger software systems for design optimization.

NASA PMARC:

MMC engineers have used the NASA panel code program PMARC since the early days of the IBM personal computer. PMARC (“Panel Method from Ames Research Center”) is an open-source program that calculates the potential flow field around complex three-dimensional bodies such as complete aircraft models. PMARC has the following capabilities:

  • Internal and external flow modeling
  • Time-stepping wake model for simulating steady or unsteady motions
  • Trefftz plane induced drag computation
  • Off-body and on-body streamline computations
  • Computation of boundary layer parameters using a two-dimensional integral boundary layer method along surface streamlines.
