Abstract: The present invention relates to automation of flow assurance simulation workflow using a web-based batch simulation scheduler. Further, the present invention relates to a system for efficient utilization of simulation resources comprising a database server; a simulator; a batch simulation scheduler; a license monitor; a launcher; a wrapper; and a debugger. The batch simulation scheduler schedules simulations on computing resources with specific input files based on user submitted information in database according to user-specified priorities. The license monitor updates the database with the number of available licenses for each feature or module. The launcher running on computing resources monitors the database for instructions from the scheduler to launch the simulations. The debugger parses the input file (s) and verifies its syntax without using a simulation license. The system utilizes all available licenses to execute the jobs thereby resulting in parallel execution of cases in the jobs.
