ROHR2 training example 12 - ROHR2 external flexibility matrix

This tutorial shows how to simplify a system with many copies of the same structure using an external flexibility matrix

ROHR2 training example 13 - ROHR2 ratcheting

This tutorial illustrates ratcheting effects due to friction.
It will show you how to create a load case follow up to simulate sucessive heating and cooling cycles.

The tutorial is split into 3 parts:

Part 1: Standard pipeline calculation
Part 2: Pipeline calculation with additonal start-up and shutdown load cases
Part 3: Pipeline calculation with successive heating up and cooling down in a load case  follow up.
