Re: Boundary Layer on a specific Wall
Hello, is there a way that I can use to exclude a specific wall in my geometry to not have the boundary layer meshing?! The boundary layer meshing was implemented for anatomic geometry so sharp corners cause the problems you are seeing. There is no way to identify which faces to use for boundary lay...

Re: There is a bug in svFSIplus
Hi Lina,
Thanks for the detailed description of this problem!
Please open a GitHub Issue for this problem so the development team can track it.
Cheers,
Dave

Re: Advice on solving convection-diffusion equation
Hi Ignacio, The svFSIplus code has support for an advection-diffusion equation, see the dye_AD example. To simulate convection set the Coupled parameter to true <Add_equation type="scalarTransport" > <Coupled> true </Coupled> ... </Add_equation> Btw, any new solver development should be done in the ...

Re: Bad Cells
Hi Stanley, Thanks for the link to the SV documentation, learn something new every day! I did not even notice this error when experimenting with the data, should be a popup really. It's not clear in the documentation what is meant by triangles that have more than one neighbor , triangles will have s...

Re: Bad Cells
Hi Stanley,
I was able to create a model using all of the segmentations on MacOS 13.5 M2.
I'm not familiar with the bad cell error. Is this coming from an SV popup window ?
Note that this project is segmented poorly and the resulting model geometry is not smooth.
Cheers,
Dave

Re: In Youtube Tutorial(13)
Hello,
It seems that you don't have svSolver program installed. Download and install the 2019 version.

Re: Unable to import dicom image
Hello,
Is this an error message from SimVascular? What version and which platform?
What is the source of the DICOM files: CT, MRI ?

Re: turbulent kinetic energy and residence time in aneurysms
Hello,
There is no output option for turbulent kinetic energy or calculate residence time.
You could write a Python script or maybe use ParaView to calculate these.

Re: Example scripts for command-line meshing
Hello, The TetGen (see https://simvascular.github.io/documentation/python_interface.html#meshing_module) describes the get_surface() method for the TetGen class that returns a vtkPolyData object containing the surface mesh with face IDs. mesh_surface = mesher.get_surface() file_name = "cylinder-mesh...

Re: experimental (MRI) backflow not described by simulations
Hello, The proper solution would be to model the renal vessels with their outflow boundary as far away from the junction with the aorta as possible. The backflow stabilization correction is only applied at the outlet boundaries. You also need to understand what might could be causing the backflow. I...
