Document Summary

Tutorial 2: modifying grid and introducing different physics models. We now consider different grid sizes, going from a base value of 0. 002 m to 0. 001 m. this will be followed by introducing a new physics model that can be used to look at turbulent flow. Delete previous 2d region by right clicking on region>orifice_plate 2d and selecting delete. Select continua>mesh 1>reference values> base size and set value to 0. 001 m. Click the generate mesh button as done in the previous tutorial. Your mesh scene should look like the following: As before, convert to 2d by selecting mesh>convert to 2d. A new region (cid:858)orifice_plate 2d(cid:859) should be created. Step 5: change physics model to physics 2d. Under physics continuum, select the physics 2d model that was previously made and click (cid:858)close(cid:859). As before, go to regions > orifice_plate 2d > boundaries > inlet > physics values > velocity magnitude >
