Change Fluid Property in Hammer

Question

Dear Bentley, 
 
 Is there any way to change the fluid property (i.e. Bulk Modulus) in Hammer? 
 I found a solution in forum in 2015 which said it's under calculation options - hydraulic, but my software doesn't show the same thing 
 Modeling other fluids or fluid temperatures - OpenFlows | Hydraulics and Hydrology Wiki - OpenFlows | Hydraulics and Hydrology - Bentley Communities 
 BTW I use academic license. My calculation option window is attached.

Thanks, 
 Shiqing

Hello Shiqing, 
 The article is referring to the Calculation Options in the "Base Calculation Options" under the "Steady State / EPS Solver" and not under the "Transient Solver" as per the screenshot you shared above. 
 In HAMMER if you changed the liquid type in the "Steady State / EPS Solver" you might need to adjust the vapor pressure in the Calculation Options of "Transient Solver" by selecting the appropriate liquid from the Liquid Library. 
 You can go through the article you found for more details on the changing fluid properties for analysis in HAMMER. 
 Hope this helps.

To add to Yashodhan's answer - the bulk modulus impacts pipe wave speed if using the wave speed calculator tool. This tool enables you to select from the liquid engineering library where the bulk modulus and other liquid properties are stored. See more here: Entering Pipe Wave Speed for a Transient Simulation
