Using Inflation with the Sweep Method in ANSYS Meshing
Hello, today I'm going to talk to you about how to create a mesh using the sweep method and also how to create an inflation. Some users experience problems with this process because the workflow for creating inflation changes when the sweep method is enabled.
Initial Setup
We will start with a simple duct. First, I will create some name selections:
- Inlet
- Outlet
Mesh Configuration
As a CFD engineer, I will change my physics preference to CFD and the sub-preference to Fluent. Let's start creating the mesh:
- Select the entire domain.
- Set the method from Automatic to Sweep.
- Keep the source and target selection as Automatic.
- Set the number of divisions to 50.
Let's generate the mesh and see the results. We see that 50 cells are created in one direction, which might be what we want. However, let's explore further by including an inflation.
Attempting Inflation
To include an inflation:
- Select the geometry again.
- Attempt to include an inflation by selecting the walls for inflation.
You'll notice a cross symbol indicating that inflation cannot be created with the sweep method. This is because the current workflow does not support it.
Alternative Approach
Let's try a different approach:
- Go back to the sweep method settings.
- Change the source to Manual Source.
- Select the manual source and set the number of divisions to 50.
Even with this method, the inflation option remains unavailable. Therefore, we need to change our workflow for creating inflation.
Creating Inflation with Sweep Method
To successfully create inflation with the sweep method:
- Select the specific face where you want the inflation.
- In the boundary settings, select the edges for inflation.
- Click Apply. Now, the inflation option will show a check symbol.
Generate the mesh again. You will see that the inflation is now created. You can also reduce the size of the mesh without changing the number of divisions by creating a volumetric sizing.
Final Steps
To adjust the mesh size:
- Create a volumetric sizing.
- Set the sizing to 1 in your string.
- Generate the mesh again.
The inflation remains, and the size is adjusted while maintaining 50 divisions in the specified direction.

Using Inflation with the Sweep Method in ANSYS Meshing Hello, today I'm going to talk to you about how to create a mesh using the sweep method and inflation.
Some users experience problems when trying to do this because we need to change the workflow for creating inflation when the sweep method is enabled. Let's start with a simple duct. I'll create some name selections, and then we'll begin. This will be the inlet, and here we'll have... now that.
Perfect. I'm a CFD engineer, so I'll change my physics preference to CFD and the sub-preference to Fluent. Now, let's start the mesh. I'll select the entire domain and set the method to sweep. I won't change the source and target selection; I'll leave it as automatic.
I'll set the number of divisions to 50. Now, let's see what happened. We have cells, and there are 50 cells in this direction. This might be what we want, or maybe not. We can play around with this. Let's see what happens if I try to include an inflation.
I'll select the geometry again and include an inflation. I'll select these walls as the walls posing inflation. However, there's a cross symbol, which means that inflation cannot be created for this case. The reason is that we have a sweep method.
If we use this workflow for creating inflation, we cannot create it. Let's try something different. If we go back to the sweep method, we can change this to manual source. I'll select the manual source, and the number of divisions is 50. Now, I don't have the check symbol for the inflation.
However, let's generate the mesh. Now, you see that the fifth division is here, or here in this direction from here to here. We'll change the direction of the divisions in the sweep method. Previously, it was in this direction. Now, it's in this direction.
However, with both directions and both methodologies, the inflation cannot be done. When we have the sweep method enabled, we need to change the workflow for creating inflation. In the geometry, we'll select the phase where we want the inflation to be created.
For instance, if we want inflation in these walls, we'll select this phase. In the boundary, we'll select edges, such as this one, this one, this one, and this one. Now, the inflation option has a check symbol. Let's create the mesh. Now, we can see how we have an inflation.
We can reduce the size of the mesh without changing the number of divisions in this direction. To do this, we can create a volumetric sizing. I'll create this and set it to 1. We'll create the mesh again. Now, the inflation is still created, and we have 50 divisions in this direction.
The size has changed. That's the way you can work with the sweep method and inflation. Thank you very much for your attention. If you have any questions, please contact us. We hope to change the future of arm & zone. Thank you for watching. Bye-bye. See you again. See you.
