Hi Adam;
Please check out the following API functions for manipulating time-series data via IFM:
IfmGetPowerCurve , IfmDeletePowerCurve , IfmGetPowerInterpolationKind , IfmSetPowerInterpolationKind , IfmIsPowerCyclic , IfmSetPowerCyclic , IfmGetPowerComment , IfmSetPowerComment , IfmFindPowerCurve , IfmGetNumberOfPowerPoints , IfmGetPowerPoint , IfmSetPowerPoint , IfmDeletePowerPoint , IfmInterpolatePowerValue
'Time Series' used to be called 'Power Functions' in earlier versions of FEFLOW, thus the 'Power' in the function names.
Cheers,
Peter
