IFM Initial Heads

I was wondering how to set initial head values at the beginning of a transient model run (t=0) dynamically using the IFM API.
I didn't come across a function description that seems to be suitable.
Does the function <IfmSetResultsFlowHeadValue> within the PreSimulation call-back do the job?
Help muchly appreciated.

FEFLOW does not distinguish between initial conditions and resulting heads internally. Thus the hydraulic-head parameter is called a process variable in FEFLOW 6, and the term 'Initial Conditions' does no longer appear.
So IfmSetResultsFlowHeadValue in PreSimulation should perfectly do the job.

Hi Peter,
thank you for the quick response.
