TransAT Tutorial Manual                                                   7.1. Oilseparation


               7.1.6    Mesh & BCs Tab

               In the Mesh & BCs tab, the domain along with the mesh are defined.

                   • If that is not already the case, select Mesh & BCs tab at the top of the TransATUI window


               Domain & Grid

                   • Click the Domain & Grid tab and set the following values for the domain boundaries in
                     the Domain section.

                     X min [m] : 0.1
                     X max [m] : 3.0
                     Y min [m] : 1.7
                     Y max [m] : 8.4
                     Z min [m] : 1.53
                     Z max [m] : 1.54


                   • Enter the following grid parameters given below to define the cell density and aspect ratios

                     Nx:   71 , Cell Ratio : 1.10 , Maximal Ratio : 4
                     Ny: 151 , Cell Ratio : 1.10 , Maximal Ratio : 4
                     Nz :   2 , Cell Ratio : 1.00 , Maximal Ratio : 1



               Grid refinements need be created to make sure that there are enough cells in the diameter of the
               outflows.

                   • Check Customized Refinement in the Refinement Type section


                   • Select X-axis then click  to create a new refinement zone
                   • Enter the following parameters in the corresponding fields then click

                     Type : Point
                     P1(X) : 1.55



                   • Select Y-axis and click  to set up refinements at the bottom pipe.

                   • Enter the following parameters in the corresponding fields then click

                     Type : Point
                     P1(Y) : 4.05
