Process mode for the H2 example simulation

The purpose of Process mode is to specify the initial pressure profile of the system. You can do this in two ways:

• Calculate the equivalent length of each section of pipe and enter the data. We entered equivalent lengths from the reference paper2.

• If the pressure profile is known from another source, specify the pressure profile throughout the system and allow the PipeFlow models to calculate the equivalent length. This approach is very useful for the tube bundle.

In this example, we use the first approach for the pipes, because the reference paper provided equivalent lengths. We use the second approach for the tube bundle, because the reference paper provided the heat exchanger pressure drop.
