Interaction of Stent with Artery and Plaque — Lesson 1

Welcome back! Now that we have gone through the representation of the stent, vessel and plaque, it is time to combine them and study their interactions. We will cover techniques like numerical contact, cyclic symmetry, stabilization, result evaluation and so on.

  • Please utilize the mm, kg, N unit system when solving the Ansys simulation models.
  • Please also note that the results you obtain in these nonlinear analyses may differ slightly from those shown in the videos. Numerical round-off due to finite machine precision can be affected by the choice of the operating system, the number of cores, and the type of parallel processing (shared memory vs. distributed memory). Moreover, nonlinear contact and solution algorithms are often improved in each version of our software, so some changes are expected when comparing results between different releases. Thus, your results may differ slightly (within typical engineering tolerances) from the presented results, but this is to be expected for nonlinear analyses, especially for numerically unstable (e.g., underconstrained) models that may be utilized in this course.
