Hi,
I am new to gmsh, so apologies if the answer to my question is obvious.
I coded a .geo file (Attached) to create 3D RVE with fibers in a matrix that
includes voids.
The process simply is :
1- Create box of the matrix material.
2- Create voids using Sphere command and BooleanDifference to remove these
from the matrix material.
3- Create fibers as Cylinders and and utilise BooleanFragments to include
the cylinders in the matrix.
I have one persistent problem, once the mesh is created the fibers are meshed
as hollow cylinders, however i need them to be solid.
Its interesting behavior. Last thing to note that mesh size affects the
outcome, for example when the min/max mesh size is 2, the result is solid
cylinders, but with mesh size of 1, it becomes hollow.
It there a way to force the meshing algorithm to mesh the cylinder as solid
object?
I have attached the .geo file, please let me know if you can help.
Any suggestions?
The geometry is a bit tricky: it's almost degenerate (with some cylinders very
close to the boundary), and the parametrization of some curves does not seem
monotonic. I've successfully meshed with the following parameters:
MeshSize{305, 310} = 0.5;
Mesh.MeshSizeMax = 2; // successfully tested with 1 and 2
Mesh.AngleToleranceFacetOverlap = 1e-6;
Mesh.Algorithm3D = 10;
