OS-E: 0700 Subcase Specific Model Change using 3-Rings

Demonstrates subcase specific model change feature. In this model, there are 3 rings of different sizes, Component A is the smallest ring, Component B is the middle ring, and Component C is the largest ring.

Model Description

The ring colors are:
  • Red
  • Blue
  • Yellow

In the first subcase, the interface fit between ring A and B, and removing ring C is simulated.

In the second subcase, the status from the previous subcase is carried over; in addition, the external layer elements from ring B is removed.

In the third subcase, ring C is added and simulation interface between all the three rings by adding another contact between ring B and C. (In this subcase, the status from the previous subcase is carried over).
