Re: Simulation User Guide Fix
Hi Justin, Thank you for your feedback. I am in the process of improving the SV documentation and would welcome any suggestions for improvements. The equations in the Simulation Guide section appear to be formatted fine with the Chrome Browser on MacOS (see attached image). Windows 10 Edge and IE br...

Re: 3D segmentation
HI Justin, The SimVascular documentation is out of date with regards to 3D Segmentation. We have recently released a new 3D Segmentation tool named **SV MITKSegmentation** that is accessible under the **Tools** menu in the SimVascular toolbar. We are in the process of updating the documentation. Sor...

Re: Meshing doesn't work
Hi Aditi, Meshing errors are currently only shown in a console window on Windows and Ubuntu. On MacOS you need to execute SV from a terminal using /Applications/SimVascular.app/Contents/MacOS/SimVascular to see the errors. Meshing errors are typically caused by problems in the model. The model must ...

Re: How to move the stent in Simvascular?
Hi Chunyu, Building a CFD mesh incorporating a stent is a bit involved. The best way yo do this is to use a solid modeler to build a solid model of the vascular geometry and the stent, and then perform a Boolean subtraction of the stent from the vascular geometry. Another way would be to use VTK Boo...

Re: CELL output as regular grid
Hi Sekeun,
This is a pretty specialize application, projecting a unstructured grid to a structured grid, SimVascualar does not have such an operation.
You can use VTK to do this using the vtkSelectEnclosedPoints class.
Cheers,
Dave

Re: Segmented mask to mesh
Hi Sekeun,
You can create a segmentation of a binary image using the level set 2D segmentation method in SimVascular. You can then create a surface from the segmentation and generate a finite element mesh that can be used for a cfd simulation.
Cheers,
Dave

Re: Running svSolver in Cluster
Hi Damian, Well, I created a VM with CentOS 7 and ran svsolver no problem with both MPICH and OpenMPI! I didn't think that would work ... The problem must have to do with setting up the environment you are running the job in to find MPI. I know on some clusters you must manually ask for certain appl...

Re: Segmented mask to mesh
Hi Sekeun, I don't quite understand your question. You generate a image mask identifying an anatomical feature (e.g. vessel lumen) like in the attached picture. But you don't want to create a segmentation based on the just the mask? You would like to use the mask as a guide for the segmentation? If ...

Re: Installation_issues_Ubuntu19.04
Hi Guillaume, It's not clear what's going on here. We have just recently found some problems with the MITK DICOM reader for CT data but I have not seen any problems with MR. Your data is detected as MR but then a reader can't be found for it so I'm thinking that there is a formatting issue with your...

Re: Running svSolver in Cluster
Hi Damian, Hmmm, I would not think that this would work, but maybe with the right CentOS it could. I'm not sure what is causing the undefined symbol: mpi_type_extent error, seems like the library you are linking to can't find this symbol, maybe due to CentOS / Ubuntu. Are you sure you are using an m...
