Dear all

I need to add water pressure as 5 bar for the supplied part. There I have to select all the surfaces which get contact with water. When I have several such surfaces, it will take considerable time and sometimes one can miss some surfaces to add. Is there a way of selecting such surfaces at once, it will save my time.

Model is attached herewith with the simulation study. This model is created using SolidWorks Premium 2011 version.Could anyone help me?

Thank you for any kind of help.
