Re: Modeling with multiples segmentations

Hello, If you create paths using the same image points then the planes should be similar. The first segmentation of a child vessel just needs to be within the lofted surface of the parent vessel. One way to create this segmentation is to copy and past a segmentation of the child vessel. Cheers, Dave

Re: svFSI Simulation Error

Hello,

It seems that the solver can't read the solver input file. Upload you SV project somewhere I can download it and I'll have a look.

Cheers,
Dave

Re: Customization of Inlet Condition Using the bct.dat File

Hi Kieun, I assume you are talking about the svSolver. To use a custom analytic shape you can create your own bct.dat file that maps the inlet flow to a velocity profile for each node in the inlet face. The idea is to create nodal velocities that when integrated over the inlet face reproduce a given...

Re: ROM running issues

Hello,

I downloaded your SV project but it did not contain a ROM simulation .romsimjob file in the ROMSimulations directory so I could not run a job to test. Please add this file.

Cheers,
Dave

Re: create data files for simulation error

Hello, Thanks for sharing your experience! There does seem to be a problem with the latest 2022.07 svSolver release on Windows. However, I am not able to determine what exactly the problem is because I can't reproduce the failure on my Windows laptop. I will try to write a shell script to check the ...

Re: Compiling Simvascular on EXPANSE (SDSC HPC)

Hi Jimmy, Building SV on an HPC cluster will be very challenging because a cluster typically does not have the graphics libraries (e.g. OpenGL, X11) needed to build SV. The compilation errors you are seeing are caused by that. There is a SV CentOS 7 version on SimTK (https://simtk.org/frs/download_c...

Re: Keywords for svpost in .slurm files

Hi Alessandro, There is no functionality in svpost to create flow files. The create-flow-files you refer to is I think a program I wrote to create flow files (see https://github.com/ktbolt/cardiovascular/tree/master/create-flow-files). I've never built this guy on an HPC cluster but you can download...

Re: Understanding NL Residuals in Simvascular History File and Setting Simulation Tolerance

Hi Flaminia, One of the benefits of open source software is that you can examine the source code to get an idea about how the code works (see https://github.com/SimVascular/svSolver). When asked a detailed implementation question I too will need to look at the source. I've been working with Simvascu...

Re: error in the simulation

Hi Simon, The message C:/Program Files/SimVascular/svSolver/2022-08-19/svsolver-msmpi-bin.exe ended prematurely and may have crashed. exit code 0 seems to imply that your simulation process was killed. You might be using too much memory, check that while running a simulation. I also wonder what happ...
