Drawdown map

I am using the FeFlow standard interface (6.0).
Is there any way I can create a drawdown map for heads in this version?

Otherwise, please detail the steps required to perform the operation by switching to classic.

Hi Tim,

In the standard interface you could use nodal reference distributions and the IFM plug-in 'Basic Arithmetic Operations', which can be obtained by asking 'support@dhi-wasy.de'.

In the classic interface, you can use the 'Special Operations' in the Postprocessor menu, either with nodal reference distributions, or as Temporal operations, choosing two timesteps for calculation.

In the next version 6.1, expression-based calculations will be availble without the help of a plug-in.
