To get the most value out of EASA, you will want to run EASAPs to generate new results, which will provide much needed information, answers to your questions or solutions to your problems. In running an EASAP, there are five main tasks that you will want to perform:
The following sections will provide further details about each of these five tasks.
EASAPs can be opened in a variety of locations within EASA. These locations include:
The methods for opening an EASAP vary somewhat by location. In the Applications Library, you click on either the title link of the EASAP or its thumbnail image both in Table View and Gallery View. In the other three locations, EASAPs are opened by clicking on an Open button () in a table column.
Note: EASAPs opened from the Application Library will contain the default inputs saved by its author, while EASAPs opened from the other locations will contain inputs made by you or another user prior to either saving or submitting the EASAP.
Once you have opened an EASAP, the next step is to enter the input data for the problem on which you are currently working. This input data can take on a variety of forms on the interface of an EASAP; for example:
For more information on how data entry will be presented in an EASAP, see EASAP GUI Components.
Tip: To minimize the amount of data entry, you may want to search My Workspace, My Results or All Results for a version of the same EASAP with similar inputs to your current requirements and open it instead of the default version found in the Application Library.
When entering numerical data into certain input boxes, you have the choice of using EASA's Expression Language instead of entering numbers directly. This capability may prove useful when you want a numerical input to be a function of a different input.
After you have spent time entering your inputs, you will often want to save your work to your workspace. To save a version of an EASAP, you either select Save under the File menu or click on the Save button ().
Every time that you save an EASAP, you will be prompted to provide a filename for the saved version of the EASAP using a pop-up as shown below.
All versions of your saved EASAPs are stored in your workspace and can be retrieved using the My Workspace page under the Workspace menu in EASA.
Now that you have entered your input data and maybe even saved the EASAP to your workspace, you will want to generate results data for viewing. Results will be generated in two possible ways:
To submit an EASAP to run, you can select Submit… under the File menu, or depending on the nature of the EASAP, there may be an alternative submission method within the interface of the EASAP itself. After submitting the EASAP, a pop-up form, as shown below will appear indicating that your submission has been successful. Click OK on this form.
Once an EASAP run has been successfully submitted, it is added to the EASAP Queue for execution.
There are several types of runs that can be submitted from an EASAP. The most basic type is the single value run, for which only one case is submitted. The other types of runs are parametric, and involve multiple cases submitted for execution. More detailed information on these advanced multiple run types of EASAP submissions is provided at Using EASAPs for Multiple Run Studies.
Submitted EASAP runs are sent to the EASAP Queue, which manages the execution of all EASAP runs submitted by all users on an EASA System. After submitting an EASAP to run, you can check on its status by selecting My Results under the Results menu in your browser.
On both the Choose Results form and the My Results page, the Status column provides information on the status of your submitted runs in the EASAP Queue. This information will be displayed in one of four different messages:
Note: Special text might be displayed instead of the percent complete number while an EASAP is running. This text is defined by the EASAP’s author.
The order in which submitted EASAP runs are computed within the EASAP Queue is not purely chronological, or “first come, first serve.” In an attempt to be fair to all users, the queue works to maximize the number of different users with runs being computed. This means that higher priority is given to newer submissions by users without any runs being computed over older submissions by users with at least one run being computed. Therefore, if a user submits a large number of runs to the EASAP Queue, other users will not have to wait until all the submitted runs are completed before their runs are computed.
Tip: If one of your runs seems to be “stuck” in the EASAP Queue, you can contact and notify your EASA Administrators of your problem. Select Support under the Help menu for a list of your EASA Administrators, who can manipulate the queue and the compute server resources to possibly get your run computed more quickly.
Similar to generating results in an EASAP, there are two possible methods for viewing results generated by an EASAP. You can either look at results in:
When an EASAP run is submitted, the results of the run are stored in the Results Library, which can be accessed by selecting either My Results or All Results under the Results Menu in EASA. To view the results of an EASAP run, click on the button found in the Results column for the run.
When using the button on the Results pages, it will vary depending on the type of run submitted (see Table of Submitted EASAP Runs). A list of the different buttons are given below:
For Parametric type submissions, you will be able to view the report for an individual run by working your way down to a table displaying a Results button () for each run.
Note: You can view results of any run before it is completed. This is especially useful for multiple-run submissions, such as a parametric study, since you can view the results from any cases that have been completed up to that point.
