Default Sets

A default set in mHARP allows users to specify default values for various analysis input parameters. Default sets are very useful in interdisciplinary applications such as mHARP where more than a single domain might provide input to an analysis. A good example is the mHARP Building Structural Damage analysis. The minimum inputs are a building dataset, a fragility dataset, a fragility mapping dataset and a hazard. A domain expert can specify "good" fragilities for a region and another domain expert can specify a "good" hazard for a region and these would be saved as a default set that users can then set when they create a new scenario. A user can now focus their attention on the task at hand (getting building damage results) by running the building structural damage analysis and setting the earthquake moment magnitude and a building dataset for their scenario. The rest was set up through the analysis defaults by domain experts. In the next sections we will discuss how to create and edit analysis default sets.

Create Default Set

  • Launch mHARP and go to Window -> Show View -> Other. You should see a dialog similar to the one below. Find the Other category and select Default Set Editor and click OK.


That's it. You don't need to specify a default for every analysis nor for every field. All required fields that are left blank will need to be filled in by the user before the analysis can execute.

Edit Default Set

To edit a default set, you will need to open up the Default Set Editor view following steps similar to the first bullet above.


You can now close the default set and the new default values are saved to the default set.

Publish Default Set

  • After creating or editing a default set, you might want to share it so others can benefit. To publish a default set, simply bring up the Default Set Editor view and right click on a default set and select Publish Default Set ( ) icon. This will bring up a dialog similar to the one in the figure below.
