It is possible, that you will get your geometry in other format? <br>
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.<br>
<br>
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).<br>
<br>

in the appendix you find my model.<br>

Yes. You can try to the first Optimize quality of tetra, or
all of them (just try).<br>
<br>
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).<br>
<br>
Or- just share your model (ply) -in order to be more precise.<br>

<div class="moz-cite-prefix">Hi Roman,<br>
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)" ?<br>
And why is reducing element size important? In my case it is
important that the object has such "90 degree corners".<br>

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

everyone, <br>
<br>
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. <br>
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). <br>
Sorry for my poor english. <br>
<br>
Regards, <br>
Steffen <br>
