How to define variable inlet velocity in SimScale in Transient analysis?

If your variable velocity can be represented by a series of constant values at specific time intervals, you can define a piecewise constant inlet boundary condition in SimScale. Here's the approach:

• Divide the total simulation time into smaller time steps where the inlet velocity can be considered constant.
• Set up a transient simulation in SimScale.
• Under the boundary conditions section, define an inlet for the fluid domain.
• In the inlet properties, you can specify the velocity value for each time step. SimScale will apply the specified velocity throughout that time interval.
