Hi all, I tried to perform a 1D ROM simulation on the demo file provided by SimVascular. I did every step according to the tutorial (link: https://simvascular.github.io/documenta ... ation.html) but I got an error message saying:

ERROR: The area of segment 'branch1_seg1' is negative.

Does anyone know how to fix this issue?

Hello,

The branch1_seg1 is negative indicates that your model is poorly defined (e.g., outlets are too small) or your boundary conditions are not correct (e.g., wrong units). This is causing the vessel ares to go negative.

Cheers,
Dave

Thank you! I changed some of the parameters and it went on well.
