[Study] Multi time resolution

[WeiyiVirtonomy]

A 2d test case of multi-time resolution contact problem

Description

The left brick represents a catheter with higher stiffness, while the right brick represents the softer arterial wall. The catheter and the aorta have contact interaction.

By using single time step size, the configuration is:

By using a dual loop, the aorta particles are strongly oscillating:
