Exporting Mesh from Pointwise to ANSYS FLUENT
 

Hi guys,

I am very new to pointwise 17 and I am trying to learn how to use it using tutorials.

I have created a 2D mesh grid using one of the Tutorials and I want to export it to the ANSYS FLUENT now. I have read many posts and help of the pointwise, but I guess those wasn't clear for me.

Can you please explain how to export it from pointwise to ANSYS Fluent? (like you are explaining to a dumb)

As what file type should I save it in Pointwise?
Where exactly do I import in ANSYS Fluent?

Thank you.

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

Thank you, I really appreciate it.

Hi,

Can anyone pls tell me how to orient 3D structured mesh in pointwise to make it right-handed?

Thanks
SD

Use the Edit, Orient command.

Thanks Jhon.
I require a more detailed description, as to which direction should the normals be oriented (inside /outside the bolck) and where should the normals be pointing at an interface (inside which of the 2 adjacent blocks)?

Can the mesh be oriented whole at a time, i.e., selecting all domains at a time and master>apply? Or should domains of an individual block need to be oriented and then another?

Thanks
SD

The I,J,K axes should be oriented to follow the right-hand rule. Other than that, their orientation is up to you. The Orient command includes an Align function that you can use to align all blocks' axes to one that you designate as the master.

See Section 4.27.2 of the User Manual for the details.

hi guys
can you compare pointwise and hypermesh and icem? wich one is bether?

I think Pointwise is clearly superior. But I'm a bit biased ;-)

Thanks for reply 🙏

RcktMan77,

May I ask if setting cell conditions is accomplished by setting 'Volume Conditions' and what are the prescribed steps to do to ensure proper mesh import into Ansys Fluent?

Thank you.

Hello Ian:

Not certain what additional help can be provided. A Volume Condition sets conditions on volume cells and a Boundary Condition sets conditions on surface cells. As for running Fluent, that's outside our expertise.

Best Regards

Thank you John. I really appreciate the help I am getting here.

hello. what is difference beetwin ansys fluent and ansys fluent(lagacy) for export from pointwise???

Ansys fluent (legacy) is an older implementation directly ported from our retired application Gridgen.

Ansys fluent is a new and improved implementation as a Pointwise plugin.

The legacy exporter was needed by some of our long time customers.

You should use the Ansys fluent exporter for new applications.
