HEC-FDA

Updated: 18 September 2015

Issue #2
Applies To: HEC-FDA Verson 1.4

Problem:

Importing a Version 1.2.5a HEC-FDA study to a Version 1.4 HEC-FDA study.

During the import process, structure modules (structure groups) are imported, but the counter that keeps track of the number of structure modules is not correct. If a user deletes any plan in HEC-FDA Version 1.4 after importing a Version 1.2.5a HEC-FDA study, then all structure modules are deleted.

Solution:

Always make a backup copy of your HEC-FDA Version 1.2.5a study prior to importing an HEC-FDA Version
1.2.5a study.

  1. After importing a Version 1.2.5a HEC-FDA study into Version 1.4, do not delete a plan because all structure modules will be deleted.
  2. If you do delete a plan and the structure modules are deleted, you should contact the HEC-FDA team at hec.fda@usace.army.mil and electronically provide the HEC-FDA study. The fix involves the underlying HEC-FDA study database and one needs to use Visual dBase or Microsoft Access to fix the study.

Applies To: HEC-FDA Verson 1.4

Problem:
Transform Flow Function - when entering or modifying a Transform Flow function the data entered is not being saved.

Solution:
  1. From the HEC-FDA interface, from the Economics menu, click Export.
  2. From the Export Data dialog box, select Frequency Curves, click Export.
  3. From the Export Data Browser, browse to the location where the file will be saved; provide a filename, click Save
  4. The Exporting Data Status dialog box will let the user know when the export is done.
  5. Using EXCEL, edit the tab delimited file that has been created. Edit the transform flow function. Save as a tab delimited file.
  6. Now to import the tab delimited file that contains the transform flow function. From the HEC-FDA interface, from the Economics menu, point to Import, click ASCII Tab Delimited.
  7. The Import Data dialog box opens, click Import.
  8. From the Import Data Browser, browse to the location where the file exists; select the filename, click Open.
  9. The Importing Data Status dialog box will let the user know when the import is done
  10. The modified/new transform flow function should be in the HEC-FDA study.

For a new function, the best way is to import the probability function with the transform flow using a tab delimited file (Steps 6-9). The user will need to setup the tab delimited file following the instructions in Appendix D, of the HEC-FDA User's Manual, pages D-17 thru D-20. There is an example transform flow in the import file shown on page D-20, Figure D-12 of the HEC-FDA User's Manual.
