Hi Reza, I assume you are talking about 2D segmentation. I can't access your dropbox. If you still have the issue, please share your SimVascular project not just the image. With the levelset method, possible reasons include: paths far away from vessel centerlines, no valid contour created with your ...

Hi Ella, In the documentation website, there is no explanation for those parameters, as we thought they were self-explanatory in cardiovascular CFD. I can explain the parameters you mentioned as below: vWSS: wall shear stress, "v" means velocity and the WSS is derived based on velocity. vinplane_tra...

We just found another bug in svSolver, and also we fixed more bugs in SimVascular, so we plan to release new versions for both SimVascular and svSolver, in a couple of weeks.

Thanks,

Hi Brennen, The non-linear residuals are based on Navier-Stoke equations (which contain non-linear terms). the number 5 for step constructions is the maximum steps. in solver parameters, we also have a few options for non-linear control: Residual Control: True Residual Criteria: 0.01 Minimum Require...

Hi Brennen, Are you using the latest version (2017.6.18)? You can find the version no. in the title of the SimVascular main window. The issues 1 and 2 will be fixed in our next release (soon). About issue 3, could you send me your project, and tell me the steps for me to reproduce the crash issue? T...

Hi Lina, If you are simulating with pulsatile flow, you can use median pressure as the initial pressure for the deformable walls. The pressure is only used for calculating initial displacement of the walls, so, just make surethe pressure value is within the physiological range. Thanks, Hongzhi SimVa...

Hi Jay, After importing a stl model, it's converted to a PolyData model in SimVascular. Currently, SimVascular can't convert a PolyData model to a CAD model. To generate centerlines for a polydata model, there are two situations: 1. the model just has walls, no cap faces (inlets, outlets)), you can ...

Within one week. What OS are you using?

Hi Ella, To run svpost in terminal, a lot of arguments are required. You can use "svpost -h" to see what options are available. To postprocess simulation results, you check a previous post: https://simtk.org/plugins/phpBB/viewtopicPhpbb.php?f=188&t=7970&p=21372&start=0&view= Thanks, Hongzhi SimVascu...

Hi Vitaly, MAXSURF is 199 and hardcoded in the source code, so you can't adjust unless you compile the source code to build your own solver. What model are you working on? Normally, for cardiovascular models, we don't have a very large number of vessels as yours; also, for very small vessels, image ...
