On request of the users an additional, combined adapter has been added, the WandaAdapter which performs both the pre-and post processing tasks and also executes the Wanda Model. Using this combined adapter is more efficient because instead of 3 separate execute activities the General Adapter only needs to execute one and as a result the Wanda Java API used by the adapter only needs to load the Wanda Model schematization once, providing considerable performance improvement, especially for a large model. The configuration example examples given on this page therefore all assume that the combined WandaAdapter is used.
Wanda model properties
Using the properties element in the combined Wanda adapter configuration, it is possible to directly set properties of the Wanda model, typically using the following property keys:
| Key | description |
|---|---|
| Time step | Time step in seconds (float) |
| Atmospheric pressure | Atmospheric pressure (float) |
| Vapour pressure | Vapour pressure (float) |
| Rheology type | "Newtonian" or "Slurry" (string) or 1 or 2 respectively (float) |
| Density | Density of the liquid (float) |
| Bulk modulus | Bulk modulus of the liquid (float) |
| Kinematic viscosity | Kinematic viscosity of the Liquid (float) |
| Visc. Coeff K in H-B model | For slurry model (float) |
| Exponent n in H-B model | For slurry model (float) |
Exception handling
Some of the exceptions that may occur during processing are logged as warnings in the configured diagnostics file without aborting the adapter processing.:
...
- key - MODEL: this setting contains the path and file name of the Wanda Model input file to open (*.wdi) The model output file
to be read by the adapter after completing the model run uses the same file name but the file extension *.wdo. - key - BIN: this setting contains the path where the Wanda model binaries are stored.
- key - AMBIENTFILE (optional): a file name mask (can contain * wildcards) used to identify files listed under exportTimeSeriesActivity
which contain ambient properties that are applied in a specific manner to all pipe objects in the Wanda model. - key - GRIDPOINTSFILE (optional): a file name mask (can contain * wildcards) used to identify files listed under exportTimeSeriesActivity
which contain gridpoint properties that are applied in a specific manner to grid points along a pipe object in the Wanda model.
In addition to the these properties listed above , that provide specific information for the operation of the Wanda Adapter, it is also possible to set general properties of the Wanda model by defining the property name as key and a float, int or int string type value. This can be useful for example to control the Time step or Simulation time used by a Wanda model.(see the table provided earlier)
