CREATING BOUNDARY CONDITION ON POINTWISE BEFORE MOVING IT TO ANSYS

The first step is to select the appropriate CAE solver in Pointwise. From the CAE menu select the Select Solver... command. This opens the CAE panel where you can select ANSYS Fluent from the list of supported CAE software. Click OK to save your selection and close the CAE panel. Also from the CAE menu you can set the dimension to 2-D via the Set Dimension sub-menu.

Next, once you are finished with your mesh you will want to set the boundary conditions specific to ANSYS Fluent on the edges of your 2-D domain(s). Select Set Boundary Conditions... also in the CAE menu. This opens the Set BC panel. Here you can create new boundary conditions with the New button, give them descriptive names by double-clicking in the name field and typing in a new name, and then set their type from the pull-down list that appears when you double-click the CAE Type field.

Once you have created the new boundary condition, you will want to select the edges of your domain(s) that correspond to that boundary condition type which you have just created in either the Display window or List panel. Once you have selected these edges, then click the check box next to the boundary condition's name listed in the Set BC panel to apply that boundary condition to the selected edges. You will see that the number next to the check box should update to indicate the number of edges to which this boundary condition has been applied.

Once you have applied all of your boundary conditions for Fluent in this manner, then you can exit the Set BC panel by clicking OK. One last thing you will want to do for 2-D meshes that consist of multiple domains is that their normals are all aligned. To do this, select all of your domains using either the Display window or List panel, and select Orient... from the Edit menu. This opens the Orient panel which will look and behave differently depending on whether you're working with structured or unstructured domains. Use this short YouTube video to help you orient your domains appropriately.

Lastly, you will export your mesh to an ANSYS Fluent case file (*.cas) which can be read-in by Fluent. Select all of the domains that you wish to export from either the Display window or List panel, and then from the File menu select CAE... from the Export sub-menu. An Open/Save dialog window will open where you can provide a name and location for where you want to save the *.cas file on your local filesystem. Click Save to save the *.cas file. This file can be imported directly into Fluent. Hope this helps
