Hello guys.

I'm trying to mesh fluid domain around duct of the propeller with sweep method. It works good, but when I try to add inflation it's automatically deactivated because of "Invalid method". I don't know what I'm doing wrong. Can anyone help me with this issue?

I'm adding a picture of inflation and sweep method details.

OK. So the answer is: inflation is automatically deactivated when the mapped face meshing is enabled.

Can anyone tell me why?

Same problem as you, mapped Faces lock inflation.
I read the Ansys Mesher User Guide, lot of informations about inflation include parameters, auto-inflation... But nothing about the relation between
Mapped Face and Inflation.

Someone can explain us the problem or an Idea to solve the problem.

I try to make my Own Mesh of A Naca Airfoil.
Here is a Naca0012 with a correct Mesh (Mapped face and Inflation I presume)

You can try some "pseudo-inflation" in such cases as yours by adding biasing and division options, but in complex geometries it will be a big problem.
I still don't know the answer for the question posed in this topic.

To inflate a sweep method, you need to name a manual source face in the sweep options.
After this right mouse button on the sweep method in the tree outline-->inflate this method.

As far as I understand:
sweep inflation works in 2d, ansys meshes the source face with inflation layers and sweeps this face through the body. (possible boundaries are only edges, not faces like in the normal inflation method)

the normal inflation method works in 3d, you can select all the faces, which need inflation

Hi
If you add inflation by RC on mesh and inserting inflation, yes it'll be deactivated automatically with either sweep mode or multizone mode. But the solution to add inflation is to do this: LC on mesh, and search for inflation tab in details view (below "outline view") and use it as you did the previous way. But there's still a weird problem. I've tried this in only one single gometry (a U-shape pipe) and it didn't make any change. I'd made the Min sizing in to a small amount, and there was already an automatic structured fine mesh with sweep method, but without inflation for edges. Then I added inflation but after generating nothing changed. It might work for you. If you tried it please let me know about the result.
And a good suggestion for you. Use "point wise" for this mesh. It's very user friendly and easy to use after watching a tutorial on youtube "getting started with pointwise" and the meshing process becomes very short with fantastic result.

All you have to do is turn on manual source and target in the weeping options. Once you have done that select the face as the geometry and the edge as the boundary.

Hi
I faced similar problem and after some trials I found the solution. In my case I have a large cylinder (pressure plenum), from which small cylindrical outlet pipes (6 nos) are projecting outward. I wish to have swept mesh with inflation in all the six pipes and unstructured mesh with inflation in the plenum. Towards this the plenum is suppressed first and all the six cylindrical pipes stay unconnected with each other. Then by Right click on the "mesh" select method and select sweep, select the pipe for body and the source face as the free end of pipe. then RC on the sweep (below mesh in tree) select inflation, select the free face and for boundary select the edge surrounding the face. Do the same for all pipes one by one. Then un-suppress the plenum and give the inflation for it and update the mesh. Hope it works for others
