When you start StarCD for a new project, you need to type
the nam e of your project in the Enter Case Name text box,
after that deselect Resume from Existing .mdl File? and Append
to Previous .echo File? and click the Continue button.
After that, 3 windows appear, the first one is the main window called Prostar, the second one is the Star GUIde window and the last one is the Prostar Output window.
In fact, to run an analysis, you just need to follow the different steps of the NAV CENTER in the Star GUIde window. Our manual is in in fact jsut a little tutorial to generate a 2D mesh with really simply boundary conditions.
You just have to enter the paramaters shown below and click Generate Mesh in the Star GUIde window.
By clicking on Re-Plot or Cell Plot in the main window, the mesh will appear in this window. After that, to save it, you need to to click on Save Model in the File menu in the main window.
Here is our mesh, it's just a rectangular parallelepiped, which is in fact a rectangle because the width is very small:
-The first step is to create two symmetry conditions.
For this, click on 1 in Boundary Region and choose Symmetry
in Define Region Type. Give a name like "Symmetry1",
in Boundary Region Name and click Apply. Click
on the Surface Based on Edges Button and click on any edge
on your surface in the main window. Do it again for the opposite face (called
-We use two outlet conditions, on two adjacents edges of the rectangle. To do that, it's the same than with the symmetry condition except you click on the Select a Zone button and not on the Surface Based on Edges button. In this way you choose a zone in the main window for your Boundary condition and every whole surfaces in this zone will be selectioned.
-We use four inlet conditions two on each edge of the other edges of the rectangle. For that we do the same as for outlet conditions.
Finally, we have the following grid with its boundary conditions:
You can check the boundary regions by clicking on Boundary List in the Lists menu in the main window.
Now, you have to check your model by clicking on the folder Check Model Setup and running Check Everything. Finally click on the All button. If there are troubles in your model, one new window will appear and will explain you what is your mistake.
Finally, to run your analysis click on the folder Analysis Preparation/Running. The most important things you have to check are Set Run Time Controls to enter number of iterations and Run Analysis Interactively where you will start your running by clicking on Start New Analysis.
Now you are in the Create Plots menu, choose your plot (contour
or vector) and click on the Plot to File and Plot to
Go in your main window and click on Re-Plot or on Cell Plot.
