Dear Developer,
I download the latest one(Windows) and have a try. However, it still filed to create data files if I use a mesh with boundary layer.
I use the Coronary Project from your course and the only different part is the mesh.
For advanced options
Global max edge size:0.075
Boundary Layer Meshing: yes
Portion of edge size: 0.60
Number of layers: 4
layer decreasing Ratio:0.80
Extrude boundary layer inward from wall: yes
Surface Meshing: yes
Volume meshing: yes
Others: no
for local size
wall_aorta:0.2
cap_aorta:0.2
cap_aorta_2:0.2
others:default
Then I got a mesh successfully:
Number of Nodes:121785
Number of Elems:677389
Number of edges:60789
Number of faces:40526
I set the same parameters as Coronary Project in Solution part. Then it failed to create data files and said " Svpre.bin stops work".
bct.dat 0kb
cap_aorta.flow 17kb
cort.dat 177kb
numstart.dat 1kb
rcrt.dat 1kb
solver.inp 2kb
test_job.svpre 2kb
I only got these files.
What's wrong?
Thanks a lot and may you a sweet day.^^
yours,
Dai

Re: Boundary layer
Hi Dai,
I tried the Coronary example using the parameters you supplied on a Mac (I don't have access to a Windows computer) and everything worked fine.
Could you please try to do the boundary layer simulation using the Demo example? If that doesn't work then I will get someone here with a Windows computer to try to reproduce the problem you are seeing.
Cheers,
Dave

Re: Boundary layer
Dear Dave,
I am afraid that there is really a bug in the Windows' one. I downloaded the SVProject and created a mesh with boundary layer. (I tried the model that came with the project.)
For advanced options
Global max edge size:0.2007
Boundary Layer Meshing: yes
Portion of edge size: 0.60
Number of layers: 4
layer decreasing Ratio:0.80
Extrude boundary layer inward from wall: yes
Surface Meshing: yes
Volume meshing: yes
Others: no
Then I got a mesh successfully:
Number of Nodes:93812
Number of Elems:529770
Number of edges:42258
Number of faces:28172
I set the same parameters as SVProject in Solution part. Then it failed to create data files and said " Svpre.bin stops work" and there was a blank in Show Details.
bct.dat 0kb
cap_aorta.flow 1kb
numstart.dat 1kb
rcrt.dat 1kb
solver.inp 2kb
test_job.svpre 1kb
I only got these files this time.
Then I tried the mesh that came with the project which without a boundary layer according to the Quick Guide. It works.
Could you please try the Windows version of the software? I'm Looking forward to your reply.
Thanks a lot and may you a sweet day.^^

Re: Boundary layer
Hi Dai,
I tried to run the Demo project on Ubuntu and it failed, looks like svpre is crashing. I'll have a look to see why it is crashing.

Re: Boundary layer
Hi Dai,
I have found and fixed the problem with boundary layer meshing, there was a bug in the svpre program (see https://github.com/SimVascular/SimVascular/issues/377).
An updated version of SimVascular will be placed on the SimTK website later this week.

Hi Dave,
Thank you very much. It helps a lot. I will give you feedback after I try the updated one.
