Mesh Size Sensitivity of the Simple Cheap Vessel Benchmark Problem

A mesh sensitization study was applied to the Simple Cheap Vessel Problem provided by Innovation Systems Software (ISS). The generations of the different meshes used in the present work are realized using the CoupleMeshing program, locally developed. This program allowed us to reduce the input of the COUPLE mesh part composed of several hundreds of lines (formatted or unformatted) in only five unformatted lines. A new RELAP5/SCDAP execution interface of the code that integrates the CoupleMeshing program has been proposed. A call is being made through this article to Mr. C. Allison to support this new interface. The results found clearly show the influence of the mesh size on the different parameters studied.
