When I mesh with the default mesher values I get regions a mesh with weird protrusions or pieces missing, as seen below:
with a finer resolution it looks worse.
These are my other parameters
Geometry
coordinates = ‘CARTESIAN’
imax = 116
jmax = 248
kmax = 116
x_max = 0.46
x_min = -0.46
y_max = 2.9
y_min = -0.3
z_max = 0.46
z_min = -0.46
cpy(0) = 2.9
ery(1) = 2.0
first_dy(1) = 0.0
last_dy(1) = 0.0
ncy(1) = 248
no_k = .False.
Cartesian grid
cartesian_grid = .True.
dim_facets_per_cell = 100
itermax_int = 10000
stl_small_angle = 0.1
tol_delh = 0.05
tol_small_area = 0.05
tol_small_cell = 0.05
tol_snap(1) = 0.0
tol_snap(2) = 0.0
tol_snap(3) = 0.0
tol_stl = 1.0000e-06
tol_stl_dp = 0.0001
use_stl = .True.
When decreasing stl_small_angle to 0.0 these mesh artifacts are removed. Increasing the mesh resolution with the default mesher parameters keep giving me bad meshes.
Can one of the other parameters cause it?
Thanks!
