Within each element in your mesh, the simulation considers material, temperature, and flow behavior to be constant. By creating a more refined mesh with smaller cells, the simulation can predict more detailed results at the expense of longer simulation times. Having a more refined mesh can also enable you to capture how temperature and flow conditions change within a body. For example, using a single mesh cell to represent flow at a narrow gate will cause the simulation to approximate the flow conditions in the gate as uniform, whereas using a more refined mesh with five or more cells through the cross section of the gate will allow the simulation to more correctly capture the spatial gradients in velocity and temperature that exist in this critical location. Modifying the mesh setup controls is optional. By default, the computational mesh is not displayed, and it is generated automatically when you execute your first simulation step. You can separately control the mesh refinement of the plastic parts, coolant parts, and virtual mold. You can also manually execute mesh generation and inspect the resulting mesh before proceeding to run a simulation. Separate controls are available for meshing of the plastic parts, the coolant parts, and the virtual mold.
