Strong imposition of Dirichlet boundary velocities in structure-preserving discretizations of elastodynamics
Cristobal Ponce, Hector Ramirez, Yongxin Wu +2
The imposition of boundary velocities in finite element models of port-Hamiltonian elastodynamics typically relies on Lagrange multipliers, yielding Differential-Algebraic Equation…
Conduction-Diffusion in N-Dimensional settings as irreversible port-Hamiltonian systems
Luis Mora, Yann Le Gorrec, Hector Ramirez +1
This work extends previous 1D irreversible port-Hamiltonian system (IPHS) formulations to boundary-controlled ND distributed parameter systems describing conduction-diffusion fluid…
Irreversible Port-Hamiltonian Formulations for 1-Dimensional fluid systems
Ahlam Ouardi, Arijit Sarkar, Hector Ramirez +1
The Irreversible Port-Hamiltonian Systems (IPHS) framework is extended to the modelling of non-isentropic fluids with viscous dissipation in the Eulerian description. Building on e…
