How do I use a different Hydra engine version for analysis?
Only one hydra analysis engine (HydraEng.DLL) is registered with Windows at a time. You can tell which hydraulic analysis engine is being used by looking in the Help / About box. To register the HydraEng.DLL: 1. Click on the “Start” button. 2. Select “Run…” 3. Type in “Regsvr32 ” and then the path to the HydraEng.DLL you want to use. OR, click on the “Browse” button and find and select the HydraEng.DLL you want to use, then type “Regsvr32 ” in front of the path that is automatically input. 4. Click ok. It should say registration was successful. If you are switching between engines very often, we can provide a special utility (Windows interface) for doing the above process.
