svzerodsolver Input File Error

[Ricardo Roopnarinesingh]

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" appearances in the solver.json to "BloodVesselJunction" as seen in the 0d documentation. Any idea why the second error is occurring as seen in the picture?

Thanks,

Ricardo

Hi Ricardo,

The first error looks like a bug in SimVascular. I'll have a look at it. To fix it, you can replace all occurrences of internal_junction with NORMAL_JUNCTION in your input file. The BloodVesselJunction element has additional parameters for 0D elements inside the junction and is not useful here.

The second error seems like a json parsing error. Can you upload the input file so I can have a look?

Thanks!

Martin

This is now fixed in SimVascular. You should be able to extract your 0D models and run them in svZeroDSolver without issues. Thank you for reporting this, Ricardo!
