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.

"The job instance became unhealthy and the job was restarted" - what does it mean and how to deal with it?

 In SimScale, the message "The job instance became unhealthy and the job was restarted" indicates an issue with the cloud server running your simulation, not your simulation setup itself.
