Modeling and discretization methods for the numerical simulation of elastic stents
For researchers simulating elastic stents, this work offers a more efficient numerical method with theoretical guarantees.
The paper proposes a new model for numerical simulation of elastic stents, proving an inf-sup inequality for finite element discretization and achieving faster simulation times despite more variables.
A new model description for the numerical simulation of elastic stents is proposed. Based on the new formulation an inf-sup inequality for the finite element discretization is proved and the proof of the inf-sup inequality for the continuous problem is simplified. The new formulation also leads to faster simulation times despite an increased number of variables. The techniques also simplify the analysis and numerical solution of the evolution problem describing the movement of the stent under external forces. The results are illustrated via numerical examples.
