Water density, gravitational acceleration and water depth is set under location.

Wave headings and periods can be set under environments.

A WAMIT task can have one or more bodies. For each body the user chooses geometry file, either low order file (gdf) or high order file (ms2). Symmetry flags and characteristic length (ULEN) can be
specified by the user. For high order geometries, several options from the WAMIT-RGKernel Interface are included. The most important of these is the possibility to control variables in the geometry file from SIMA.

Irregular frequency removal (both using gdf-file and automatic discretization) and trimming of waterline can be controled in the body editor. Other input in the body editor includes:

The calculation parameters are separated into two tabs; one for the POTEN module and one for the FORCE module.

Options in the POTEN tab includes:

In the FORCE tab, the user can specify which hydrodynamic coefficients should be calculated. In addition, there is a possibility to add single field points, or sets of field points. A set of field points is a rectangular box with dimensions, position and resolution.

The body geometry, field points, sea surface and seabed are visualized in 3D. Whem the body geometry is specifed by a low order gdf-file, SIMA will use this file for visualization. If the geometry is a high order ms2-file, SIMA will run a minimal POTEN calculation in order to obtain a low order representation of the geometry to be used for visualization.

The obtained hydrodynamic coefficients can be inspected using plots and can easily be compared with other hydrodynamic data in SIMA.

Workflow in SIMA is a powerful tool for combination of SIMA tasks. It is a graphical scripting environment, which looks similar to the post processor. Workflow can be used to run external programs
and for automation of complex simulation tasks and result generation. A new workflow node has been implemented as part of the current project. This node allows WAMIT to be run in sequence with SIMO and/or RIFLEX, such that the SIMO (RIFLEX) simulations will be automatically updated with hydrodynamic coefficients from WAMIT.

A standardized hydrodynamic analysis report may be generated as part of the WAMIT analysis. Under Model > Calculation Parameters > Report Parameters, the user can choose to generate a report and which results to include in the report. The generated report is found as part of the WAMIT result.
