Based on the numerical tools developed in past projects carried on in collaboration with MOXOFF in the framework of a long lasting collaboration with Tetra Pak Packaging Solutions, a new research activity has been started focusing on the adoption of transpiration boundary condition for fluid-structure interaction simulations of the forming and filling process in liquid food packaging systems. This simplified FSI approach will allow to simulate on a fixed grid the elastic wave generated by the forming of the package which propagates along the carton tube on a fixed grid.
