Hi,

i have a little trouble. I need to generate a pipe to an internal simulation.
At first, i try to generate a rectangular pipe with Salome.
I create a box, then i explode all the face and finally i export all the face in stl file.
After that i rename the solid in all the stl and finally with
cat constant/triSurface/pipe/* > pipe.stl

i create my stl file with all region defined.

The procedure works fine with the box, but when i try to do the same things with the cylinder, the result of the
cat constant/triSurface/pipe/* > pipe.stl
is an open file.

If i did not name the father stl (eg. the Inlet stl instead of strat with" solid Inlet" start with "solid") the resulting stl is closed and well defined, but without region defined.

If someone have also any advise to create a multi region stl or a multiregion obj with ProE or Salome, or any tutorial case guideline ecc... i would be grateful to follow the suggest.

At the end, i need only 3 region, Wall, Inlet and Outlet.

Hello Francesco,

For what seems to be a rather simple geometry, I think that you can refer to the following tutorial: https://www.youtube.com/watch?v=1zQbU-E4k1U

I also faced the same problem with exporting faces of a solid as STL from Salome. This will occur every time you try to export circular shapes or curves, unfortunately. I noticed that Salome has very poor capability when it comes to exporting to faces to STL. However, if you mesh directly from Salome you will end up with a mesh that can be directly used in OpenFoam using ideasUnvToFoam.

Hope this solves your problem,

Florian

Hi Francesco,


Did you solve the problem ?? Can you tell me how to ?

I also used salome to make a simple geometry, exploded its faces, saved each surfaces as individual stl files and then manually combined them into one stl (as you did). When i do a surfaceCheck, i always get that my stl geometry is not closed.

I am able to successfully mesh it using cfmesh tool !! But checkMesh fails

***Total number of faces on empty patches is not divisible by the number of cells in the mesh. Hence this mesh is not 1D or 2D.

I have attached the case file in case some one wants to have a look.
