Configuration for svOneDSolver input file

[Bojian Qu]

Hi there,

I am playing around with the test cases for svOneDSolver, however, when I want to change the parameters I realized that I do not know what those numbers mean (e.g. the series of numbers after MATERIAL). I would like to know if there are any guidance or instructions for the configuration of the input files.

Thank you!

Hi Bojain,

Have a look at the 1D solver documentation here https://simvascular.github.io/documenta ... user-guide.

Cheers,

Hello,

Are there any instructions for the units of the input/output parameters? For example, if my input data is volumetric flow rate/pressure, what unit should I use? Thank you!

Happy New Year!

Hi Bojian,

The 1D Solver documentation has a Units section that states

Code: Select all

All model quantities and associated boundary conditions are specified in CGS units.

Hi Dave,

Thanks for your quick reply! I just went through https://simvascular.github.io/documenta ... #1d-solver but did not find information about units, I am wondering if I went to the wrong page. Can you provide a link for that? Thanks!

Best regards,

Hi Bojian,

The Units section is at the beginning of the ROM Simulation documentation. See https://simvascular.github.io/documenta ... troduction.

Hi Dave,

Got it! Thanks! I have another 2 questions related to the theory:

1. at each time step, there might be several iterations, does it related to the outlet boundary conditions (as I know, BCs are usually solved by iterative methods like fix point method)?

2. currently I only ran the simulation for one cycle, I would like to know how to specify the (max) number of time cycles so that I can have a converged flow

I am a freshman in this area, thanks for your kindness and patience!

Best regards,
Bojian
