User Data

Arbitrary nodal or elemental distributions of user data can be created via the Data panel context menu. They can be assigned and visualized like the ’reg­ular’ FEFLOW parameters, but the distributions are currently limited to time constant data.

User data can provide input for the FEFLOW Expression Editor (e.g., for defining kinetic reactions in multi-species transport), they can be used for stor­ing the data needed by FEFLOW plug-ins, or for comparing the model results to certain reference conditions.

User data can also be expression-based parameter distributions. In this case, the values of a distribution are calculated on the fly based on the user-defined expression. Expression-based distributions can be used, for example, to dynamically plot the water table drawdown at different simulation times.

FEFLOW offers a set of predefined distributions to display the error norms (normalized predictor-corrector errors) for flow, mass, groundwater age and heat simulations. In transport models with multiple chemical or age species, a separate distribution for each species is available.
