      Hello, I'm using Ansys workbench and I don't know how to apply commands for pipe elements. I have a pipeline model shown in the figure below.

      It's confusing to have to specify a free surface when the piping system is closed and all you want is to include the weight of the internal fluid. It's required though (to compute hydrostatic pressure), so if the largest z coordinate of your nodes is 10.0, the command you started would be: SFE,ALL,3,PRES,,10.1. Since you specified MINT=3 in your SECDATA command you need to have a material property 3 defined with a command like MP,DENS,3,9.34e-5 ! water in lb-in system. n
