Hello,
It is possible, that you will get your geometry in other format?
In your "ply" there is already a surface mesh given. Try maybe use STEP,
IGES,... as input- then it is easer to recalculate the surface mesh.
In case of need of usage of "a dead mesh" - maybe try first to remesh it
(i.e. in blender with modification Remesh) and/or clean it (removing
double vertexes and edges).

Hi,
in the appendix you find my model.
Thanks for help!!

Hello Steffen,
Yes. You can try to the first Optimize quality of tetra, or all of
them (just try).
I don't know how your model looks like. If the elements on the
surface are too big, then the solid elements (probably tetragonal)
may be with intersecting edges or faces. Therefore the reducing size
of element may help (especially on the surfaces).
Or- just share your model (ply) -in order to be more precise.

Hi Roman,
when you say "enable option: optimize", you mean" Tools -> Options
-> Mesh -> Advanced -> Optimize quality of tetrahedra, Optimize
quality of tetrahedra with Netgen, Optimize high order meshes
(experimental)" ?
And why is reducing element size important? In my case it is
important that the object has such "90 degree corners".

Hi Steffen,
If your volume is OK (is really a closed one) - try to:
1. Reduce element size (especially in a curved shapes)
2. Enable option "Optimize" - in mesh options

Hello everyone,
I'm a gmsh beginner and I want to create a 3D volume mesh out of a
given surface-mesh but I got the error message as seen in the
subject. You find my .geo file in the appendix.
Can anyone tell me what I have to do to create a 3D mesh? I even
can't figure out where the intersection are located (don't know
how to read the intersect.pos).
Sorry for my poor english.
Regards,
Steffen
