Mesh for component 1 was created incorrectly.

The patch(es) "1:Part_Studio_1_-_Outlet" has/have not been found in just created mesh.

There might be two reasons for that:

- Either the patch is so small, so the it was not possible to properly mesh it.

Check the patch visually, and also its meshing parameters.

- Second reason might be, that this patch is located outside the meshed geometry, and therefore cannot be meshed.

Again check the patch visually.

CFD meshing failed

I originally had this error on the Inlet patch, I don't know what I changed to correct that (nothing I believe)

The patch is not small, it appears water tight. It comes from a watertight model.

The patch is within the meshed geometry.

I've not had this error before, I've not struggled with meshing previously.

Hello again, 

I was wondering also if boundary layers are mandatory to capture precisely the turbulence near the walls or if a good refinement can be satisfying? As soon as my geometry is getting complex, my boundary layers start to collapse at certain locations on the walls

I am using a k-omega SST model with a standard wall function, so my simulation should be quite flexible with y+

Thank you

Alex

Hello everyone,

I am currently trying to reduce my number of cells on my mesh and I was wondering how to implement and control an expansion ratio on TMESH? to have a coarse mesh that becomes thinner linearly along a pipe for example

Thanks

Hello, I am very new to CFD and simulations, I am trying to simulate the power output of a kaplan hydro turbine. I have made the geometry, but when I try to mesh it, after 15 minutes it fails. Is there any function in TCAE that I can use to check the mesh, I think it might not be water tight, but I don't know where. Also, the setup check passes without errors.

If you need any more information, please let me know.

Thank you in advance.

Hi everyone,

I am thinking about using the TMESH module to mesh my geometries via SnappyHexMesh and I was wondering if you have any recommendations (regarding the values and significations of the different parameters for example)? Any advice or material would be really helpful.

Thank you very much and have a nice day,
Alex

What is your recommended tool flow from Solidworks to TCAE that preserves surface names (inlet, outlet, walls etc) ?

My understanding is that unfortunately Solidworks does not preserve surface names when exporting the model as an STL file and exporting surfaces as separate STL files will produce non-conformal vertices.

Does one need to go through a third-party mesher ? I believe the Solidworks .step export preserves surface names. Is the recommended tool flow to go through a package such as Salome to create separate (but conformal) stl surface meshes ?

Hello,

I wanted to know if turbogrid mesh in .cgns was compatible with TCAE?

When I try to import it, i get the error "The mesh has invalid format (sees picture).

Thanks in advance for any help.
