Hi Arjan,
thanks, but I have already tried vmtksurfaceremeshing with different
options but it does not work as well.

Hi Jan,
Try vmtksurfaceremeshing instead of vmtksurfacetriangle before
generating the volumetric mesh. The large aspect ratio of the
triangles is likely what throws off vmtkmeshgenerator.

Hi,
I am trying to create a cylinder mesh with boundary layer cells.
The created mesh looks fine except the fact that there is no
boundary layer created. As a starting point I use an open,
non-capped cylinder surface created with DOLFIN (attached to the
mail). Then I use the following commands.
vmtk = []
outfile = "cylinder.xml"
outfiles.append(outfile)
vmtk.append("vmtksurfacetransform -ifile cylinder.vtp
-rotation 0.0 0.0 90.0 -translation 0.0 %f 0.0" %float(height/2))
#vmtk.append("vmtksurfaceviewer")
vmtk.append("vmtksurfacetriangle")
# Mesh generator (comment out unwanted lines)
cmd = "vmtkmeshgenerator"
cmd += " -edgelength %f" %0.11
cmd += " -maxedgelength %f" %(1.2*0.12)
cmd += " -minedgelength %f" %(0.8*0.12)
cmd += " -boundarylayer 1"
cmd += " -thicknessfactor 0.1"
cmd += " -tetrahedralize 1"
vmtk.append(cmd)
vmtk.append("vmtkmeshwriter -entityidsarray CellEntityIds")
vmtk = " --pipe ".join(vmtk)
vmtk = vmtk+" -ofile %s" %outfile
print vmtk
subprocess.call(vmtk, shell=True)
Does anybody understand why there is no boundary layer created?
Maybe it has something to do that the surface consists out of very
stretched triangles after the command "vmtksurfacetriangle".
Thanks a lot in advance,
Jan
