Example SEAMCAT scenarios and supporting documentation
When a SEAMCAT user saves the content of an active simulation workspace, i.e. the simulation scenario, it is stored in a special file with extension .sws. This is a SEAMCAT-specific file extension used to identify Seamcat Work Space files, which, as their name suggests, contain all input parameters making up the simulation workspace.
If the workspace is saved after completion of simulation, also the results of the most recent simulation are stored in the .sws file. Once created, these .sws files may be later loaded into SEAMCAT (by process of Opening the workspace) in order to continue working with the relevant workspace/scenario, or they could be shared with other users as means of sharing experience or allowing cross-checking of simulation results.
Below are provided some of the classical example workspaces, which may be used by beginners when learning SEAMCAT. After downloading, unzipping and storing those .sws files on your PC, you can at any time load them into SEAMCAT via menu option File/Open? workspace.
Note: Before trying to load and simulate example scenarios, please read the guidance on using example scenarios (2MB) about principles of SEAMCAT operation and about using and interpreting the attached scenario examples.
