In the field of paper-based packaging, the simulation of complex material - machine interactions has proved to be a key ingredient for improved design of faster, robust systems, to enhance the quality of the final product. The next challenge for the industry is represented by the worldwide discussed - and non further postponable - need to develop recyclable and sustainable materials, reducing the amount of wastes and plastics.
For liquid food packaging, a capability for properly modelling fluid structure interaction is essential in order to evaluate aesthetic defects, investigate integrity issues, predict the amount of volume in each package and scout the performances of new materials.
The engineering problem is interesting from the constitutive point of view (non traditional fiber-based materials), the structural point of view (thin and flexible composite structures are involved), and the fluid point of view, as the process is highly non linear and the interaction with the filling system leads to a strongly coupled problem.
The co-simulation approach between Abaqus and Xflow has been successfully employed, exploiting the particle-based Lattice-Boltzmann technology to face the criticalities in the interaction: the continuously changing, closing and splitting shape of the domain, which naturally leads to converging issues and extreme mesh morphing with other classical CFD methods.

Thanks to Xflow and Abaqus teams for the amazing support: Giuseppe Trapani, Lorenzo Maria Pii, Marco Stevanella and Margherita Coda.
