Re: How to get branch outflows from svzerodsolver

I get a Segmentation Fault when I try to use the get_full_result() function. Here is the .json file I am using https://drive.google.com/file/d/1Bgy_eR ... sp=sharing. This file does work with the archived version of the 0d solver.

Re: How to get branch outflows from svzerodsolver

I am getting the same map::at error using that syntax. The only flow I can get is the branch0_seg0 flow.

How to get branch outflows from svzerodsolver

Hi, I am trying to find the right syntax to get the average outflow for individual. I can get the inflow using solver.get_single_result_avg("flow:INFLOW:branch0_seg0") but how would I get the outflow average for different branches? I've tried a couple different passes and keep getting a "map::at" er...

Calculating Cap Flows Using Post Tools

Hi,

I am trying to calculate cap flow rates through the command line. There is this directory: https://github.com/ktbolt/cardiovascula ... flow-files that is used for this but I am getting make errors. Is there any other method for doing this using SV tools?

Thanks,

Ricardo

svzerodsolver Input File Error

Hi, I am running into an error when trying to run the svzerodsolver using Ubuntu 22.04. I initially made the solve .json file in the gui and then ran the solver through the terminal where I was coming across the first internal junction error seen in the picture. I then changed the "internal_junction...

Using Externally Generated Centerlines in the 0D Simulator

Hi, I have a complex heart-to-brain arterial geometry that SimVascular is unable to generate a centerline for. Using a module in 3D slicer, I was able to extract the entire centerline for this arterial pathway. I ultimately want to use this centerline to complete 0D simulations for resistance bounda...

Re: Generating Centerlines to Complete 0D Simulation

Hi David,

If I were to generate separate centerlines, how exactly can I merge them and retain the cap IDs, branch IDs, etc. that come with the generation of a full centerline? Is there a way to merge them using Simvasular or would this have to be done in paraview?

Thanks,

Generating Centerlines to Complete 0D Simulation

Hi, I am trying to generate the centerline of the heart-to-brain pathway to complete 0D simulations (attached picture shows the geometry). This pathway is pretty complex and I am not getting any errors when I try to generate the centerline but it will just continue running for an indefinite time wit...

Re: Gradual Mesh Refinement

Hi Dave, This is what my results were looking like with spheres, I wanted a tapering mesh to account for the outer regions of the stenosis. I had to use three spheres with different edge lengths centered at the same point to accomplish this but the mesh has many strange spots. I tried using radius-b...

Gradual Mesh Refinement

Hi, I am trying to refine a mesh gradually for only a certain region of my model. The picture shows the region where I would want this gradual refinement to occur with it being the a average edge length at the border of this region and then gradually refine to a very small edge length in the region ...
