For the definition of time-varying material properties, FEFLOW 6.1 provides multiple settings and convenient import and assignment options: Time-varying values can be assigned manually if a parameter has been made transient before. Manual assignment from time series is also available following the same workflow as for the assignment of transient boundary conditions. Automatic map-based assignment via the Parameter Association dialog supports multiple data formats: Map data can be assigned to the currently selected time, different attribute fields can be assigned to different time stages, time/value pairs can be linked to a parameter and time-series files can also be joined to imported maps. Additionally, assignment via the new Expression Editor is also supported. Refer [url=http://american-writers.org/]custom essay writing service[/url] for more details.
