Hi Nolan,

And what version of svSolver is installed? Do you have MPI installed?

Cheers,
Dave

Hello Dai, SimVascular does not calculate particle residence time, that needs to be preformed on simulation results (velocity field) using post-processing software (e.g. ParaView). The Shadden Lab FlowVC software can calculate particle residence time. See https://shaddenlab.berkeley.edu/software.htm...

Hi Dylan,

What version of SimVascular / svSolver and which OS are you using?

It might be that there are bad elements (Jacobian <= 0) in your mesh. You can check using ParaView.

If you want you can put your project on DropBox and I'll take a look.

Cheers,
Dave

Hi Nafiseh, I have created a Python script called contour_distance.py that is used to calculate the distance between the centers of contours created in the SimVascular SV 2D Segmentation s module. It is not exactly what you want but it is close. I will be adding other scripts soon, need to create a ...

Hi Dylan, You can use the bct.dat file to apply a patient specific velocity profile to an inlet. See http://simvascular.github.io/docsFlowSolver.html#bctfile. The SV Simulation module will create a bct.dat and bct.vtp files when you select Create Data Files for Simulation . After doing that you repl...

Hi Anthony, Thanks for the new models! I was able to load the all models into SimVascular and extract the faces correctly, although they were not classified correctly as cap/wall, had to manually set the face names and type (cap/wall). The CentreAlign model has duplicate faces for the interior becau...

Hi Nolan, There are some known problems with running simulations from the GUI. Before I can help you I need to know what version of SimVascular you are running and on which OS. Have a look at these links, they may apply to the problems you are experiencing https://simtk.org/plugins/phpBB/viewtopicPh...

Hi Nafiseh,

There is currently no functionality in SimVascular GUI to measure the distance between control points along a center line.

It might be possible to do this using the SimVascular Python interface, I will look into that.

Cheers,
Dave

Hi Anthony, I was able to read in the Parasolid files (after renaming them to ._xmt_txt) but the SV Model module did not extract the faces correctly. The models are very small so I think there may be a scaling issue. Could you please scale them by 100 and then write them out as ._xmt_txt files and u...

Hi Maria,

You are probably having problems running from the GUI because it is not using mpiexec.mpich. You can set which MPI executable to use from the Window menu in the SimVascular toolbar and then selecting Preferences -> SimVascular Simulation.

Cheers,
Dave
