Typical work flow when simulating with SEAMCAT
A typical work sequence when using SEAMCAT for compatibility analysis would typically involve following stages:
- Create or update a simulation workspace,
- Set Simulation Control parameters,
- Perform event generation through simulation management commands,
- Analyse event generation results, eventually modify input scenario and re-run the event generation,
- Perform one or more interference calculation runs,
- Generate a simulation report.
In addition to these basic steps, some other useful steps may be used for different purposes:
- Save workspace as an XML compliant file for later (repeated) work or for sharing with other users,
- Create or update elements in the equipment library for repeatedly used equipment types,
- Import scenario data from legacy SEAMCAT-2 scenario text file.
- import library
