Implementing Time Varying Inlet Condition

Hi all,

I am new to HiFiLES. I am working on a project that requires modelling of a time-varying inlet velocity condition. 

It seems like this feature is not implemented yet. If I need to write some code to support this feature, is there any place I can start with? I would really appreciate if anyone experienced with HiFiLES can shed some light on this.

Regards,
Jack
