Connect inflation layers around a corner between two split bodies

Hi, 

Thank you very much for your question. 

Unfortunately, it is a bit hard for me to understand the block topology in this case. In other words, I am not understanding where each block ends. Is there any chance you can post some additional images to understand this; or perhaps a very simple Fidelity Pointwise file showing this particular topology? 

In addition, it seems that you are using a regular extrusion to create the boundary layers. Have you tried using the T-Rex algorithm for this? 

Thanks much!

Hi,

of course. I am using a CAD model and create the blocks from its topology.

Here you can see the white part. This should be the block with inflation layers defined as a porous volume.

The other part above is a different block and both inflation layers should be connected.

The connected inlation layers should be around the edges like the red lines you can see here:

I haven't tried T-Rex for this yet, I only used the normal extrusion. Do you think this would work better?

Thanks for your help!

Hi, 

Thank you very much for the information. 

Yes, I would recommend using the T-Rex algorithm as it will allow you to create the grid that you are looking for in a fraction of the time. Furthermore, I would also recommend using the Automatic Surface Mesh (ASM) and Automatic Volume Mesh (AVM) tools to complete the grid in a fraction of the time. 

Please note the following:

• The first step when creating a grid is "preparing" the CAD data for meshing. This includes assembling everything into a single watertight solid model and assembling the quilts as needed to defined the desired meshing regions.
• Once the above is done, you can use ASM to quickly create the surface grid (domains).
• Once you have the surface grid, you can use AVM to create the volume grid (block).

If you are not familiar with the above workflow, I would recommend reviewing the following:

• Basic Concepts: https://youtu.be/7ynTrsuG80I?si=o1EiaEc-raqmO8Wg
• ASM: https://youtu.be/VmAYwRbChMk?si=7_cfopgR3sMwEI_O
• AVM: https://youtu.be/EU1Cb2KeK-U?si=UOangATVOOK4iZCw
• Also note that you have a wealth of material in the User Manual (Help, User Manual) that will guide you through the most efficient mesh generation process. 

I hope this helps. 

Hi,

Thank you for your help.

I am aware of the workflow you mentioned above. I only looked for a smooth way to connect both inflation layers.

I will try the T-rex algorithm.

Thank you very much.

Hi, 

Thank you very much for your quick reply. 

It is good to hear that you are familiar with the recommended workflow.

You will likely generate the smoothest (and faster) grid with the use of ASM to create the surface grid and AVM to create the two blocks. Inside AVM, you will be able to set up the T-Rex algorithm for each block with the corresponding boundary conditions.

Thank you very much for your time.

Hi,

I tried T-Rex several times and got the following problem now:

As you can see, the inflation layers alsways end in the edges between the blocks. (The porous body is between the red lines, the other 2 bodies are fluid)

Is there a specific setting to connect it around the corner and also between blocks in general?

Thank you!
