The aim of the simulation is to study the behavior of a particular arrangement of a sealing system made of a Toroidal Spring Coil encapsulated in an thin casing, which is provided with a circumpherential cut to permit the pressure fill it inside.

The mechanical simulation implemented in COMSOL Multiphysics® software is necessary to understand the displacements and stresses of the structure under a pressure on the top of the casing, pushed by a flange.

The main interest is to establish what is the required gap to be assured between the sealing-system and the lateral groove surfaces; any possible supplementary lateral contact shall be - in fact - unwanted to assure a proper functionality.
