End of solving but sometimes the solution may be converged as earlier before completing given iterations. click on calculate.Īfter solving a graph is plotted. It is recommended to give value more than 50 for steady state solution. As concerned with 2D more iteration value can be given. Now double click on Run calculation and give the number of iteration to be done. You have to wait until the initialization is complete for 10 steps. Double click on initialization and choose hybrid initialization and hit initialize button. On outlet check the pressure-outlet and gauge pressure is zero. In cell zone condition make sure the surface body is fluid.ĭouble click on boundary condition and select inlet (double click) make sure to check the velocity inlet and enter the velocity value. Next double click on material ans select air, change the constant density as ideal and hit change/create and press close. As this is example I use k-epsilon and hit ok. You must have knowledge with these model types and when should be used. Our model is gonna be steady state with no gravity included with all set, double click on models (left side of page) we are going to change viscous to k-epsilon. This opens up a window and wait till the model gets loaded and stays still. You can check the double precision and select the number of cores to be used for solving and hit ok. Now double click on setup, this opens a fluent launcher. All terms related to CFD like viscosity, ideal gas, and other constants. This is the important step in CFD Fluent. These both are controlled in under a same window. #Ansys spaceclaim 2d updateAfter update close this window and you must see the another check mark next to mesh. ![]() After finalizing your mesh click on update to update your mesh onto mesh on workbench. With each mesh elements of 0.35 mm took me 10 seconds only. In the above I used face meshing (select one face of the 2D model) because structured mesh cause good result and reduce time of meshing. After a continuous iteration my model mesh values are below: Meshing is a continuous process which involve the clarity of model and solution. There are only two steps that must be carried. Now close the design modeler and on the workbench you must see the green check mark next to geometry and double click on mesh. Then select concept -> surface from sketch -> select any one line from sketch and hit apply and press generate or F5. Now exit the sketching by clicking the modeling next to sketching. Note: This might be difficult for first time user but try those, it would be really easy for well versed. Now draw a 2D shape of nozzle which look like: Mark dimensions and control values from dimension tab. You can use line or basic shape from draw tab. Note: You have to clear with sketching or any model can be imported ( will be thought later) Now from left side select any one plane (in this case XY Plane) and then look at face/plane/sketch and the select sketching A home screen of design modeler looks like this: Make sure about geometry units from units tab set as millimeter (in this instance). But can be changed to open in design modeler.Īfter double clicking or to be on safe side right click and select edit geometry in design modeler. Iam using design modeler for latest version ANSYS by default opens up space claim. Mostly CFX is ignored because it is not supported with 2D models but good for mesh moving methods (will be thought later).ĭouble click on geometry. Note: Make sure to open CFD Fluent not CFX. I name this as Tutorial 1 or can be left default. Open up your ansys workbench and drag the CFD Fluent onto the workspace or double click on it. ![]() Iam going to create the nozzle with the air velocity inlet (ideal) and pressure outlet. In this tutorial we will discuss about the 2D problems which involve defining boundary condition and solving them. ![]()
