Dear SimVascular team,
I installed the sv1DSolver package for my Mac 10.12.6, but I could not find it on my computer. Searching the whole Mac does not give me any results except the installation file or past SimVascular projects. I attached the basic system overview of my mac below. Could you help me solve this problem? Thank you very much!
Best,

Hi HmuUCSD,

The 1D solver is installed in /usr/local/sv/oneDSolver.

Cheers,
Dave

I found the file. Thank you!
Could you show me how to use the sv1DSolver? I have the input file ready.

Execute the command

Thank you for the help! The solver works, but it gives me an error message shown below. I double-checked my input file but could not find the source of this error. Can you help me with that? I also attached my input file as a reference.
Thank you very much!

Hi Hao,

It seems like your command doesn't use your input file. It should be something like
Always save your input file as pure text (e.g. .txt). The .rtf file format contains additional information that the solver can't read.

I replaced the tabs in your input file with spaces and the solver can now read the file (attached). However, the first time step doesn't converge. Please check that all your parameters have the correct unit (inflow, boundary conditions, material).

For reference, I attached one of my input files (aorta). You can also have a look at the test cases here:

Thank you very much!
Do I need to put my input file and the solver in the same folder?

No. You can provide the absolute path to your solver input file.

Hi Martin,
I double-checked all data in my input file, but I still got NaN soon after start of simulation. Do you have any suggestions? Thank you very much!
