The red plot is the plot of the Theta and Phi Pixels of 1 and the black one is for the Theta and Phi Pixels of 2 which provides a more accurate result. The shadow behind the house is visible due to its lower temperature in relation to the parts exposed to sunlight.įinally, the temperature in the middle line of the house has a trend like the following plot, increasing as it gets close to the ceiling. Also, a wake at the right side of the house is formed, making the flow circulate. ConclusionĪt the end of the solution process, two-dimensional contours, contour lines, pressure, streamlines, and vectors related to the airflow are obtained.Īs can be seen in the contours, the house’s roof (the side exposed to the radiation) gets warm by solar radiation, and the air inside the house starts to move due to the buoyancy effect. Click Move in the Edit group on the Design. In SpaceClaim, click the box next to the annotation plane so it is visible. Driving changes with annotation dimensions. You can also use annotation dimensions to drive changes in ANSYS. Using groups and dimensions in ANSYS tutorial: Step 6. Eventually, the difference in the results is investigated. Also notice that when you click on the groups in the Groups panel, you see the dimensions specified in ANSYS. Two simulations are carried out for the current problem with the Theta and Phi Pixels of 1 and 2. The Also Discrete Ordinates (DO) model for simulating Solar Radiation is used. Thus, the gravitational effects shouldn’t be denied. It needs to be mentioned that Natural Convection is dominant in this problem. The pressure-based solver is employed due to the incompressibility of the air. The elements are all unstructured, and the number of them is 696,480.

ANSYS Meshing software is used for generating meshes of the solution. FLUENT in Workbench Users Guide and the on-line documentation for ANSYS Workbench. The geometry of the solution is a 3D rectangular domain modeled by ANSYS Design Modeler with 24m, 11.6m, and 19m in X, Y, and Z directions, respectively. In this tutorial, we will create the geometry from scratch in ANSYS. However, you should be advised that raising the pixelation raises the calculation cost.

Raising the pixelation requires less computing work than increasing the divisions, which requires more work. The inside air is affected by the temperature of the walls and roof and moves due to the convection between them.Īlso, pixelation is used in this problem which is advised for simulations with symmetry, periodic, or semi-transparent boundaries and will produce acceptable results. In this project, a gable house in the rectangular-shaped domain is modeled, and the radiation of sunshine on it is simulated while the wind is blowing into the domain from one side. The different times of the day, radiation, convection, and conduction affect the temperature of the ground, while the wind’s direction can change.
