This blog is the continuation of the series of blogs on the pump cavitation analysis in ANSYS CFX and automation of this process by using CEL (CFX Expression Language) and Perl script. The previous blog can be found under the following link;
In the recent blog we are introducing to the second step in the pump cavitation analysis in ANSYS CFX, i.e. the cavitation model will be turned on and the solution will be initialized by the results from the step 1 (please refer to section for details).
Step 2: High Pressure Simulation of Pump with Cavitation Model turned on
1.2.12 Saving Case File with new name:
Open the “CFX_CAV_Off.cfx” file from the previous run with the Cavitation model turned off.
Go to: File > Save Case As…
Specify the file name as “CFX_CAV_On.cfx” and specify appropriate location and click Save.
1.2.13 Editing domain settings:
Double click on any one of the three domains i.e. InletExtension, Impeller or OutletExtension; or right mouse button on any of three domain names and click on Edit
This will open details window for that Domain, select Fluid Pairs Model tab, use the following settings and click OK.
1.2.14 Saving Case File:
1.2.15 Defining run and starting Solver:
Specify the name and location of the definition file and click Save.
A new dialogue window will open; Select the solver input file and working directory location, this time we are initializing the solver with the converged results from the previous analysis from (Pump Cavitation Analysis in ANSYS CFX (Part I)).
Specify the following settings and click Start Run.
