Fiber direction for HGO Model

Post by Aditya Bantwal » Sun Jun 04, 2023 2:58 pm

Hi,

I am trying to use the HGO hyperelastic model in svFSI.

As you know, in the svFSI.inp, I need to provide the fiber direction:

intel.png (3.48 KiB) Viewed 193 times
.

How do I provide the fiber direction for the following case?
fiber.png
fiber.png (100.29 KiB) Viewed 193 times
The angle gamma I would like to use would be: 49.98 Degrees.

PS. The case is from the original paper describing the HGO model: https://royalsocietypublishing.org/doi/ ... .2005.0073

Looking forward to your help.

Thanks,
Aditya

Hi Aditya,

You can input fiber directions using a file. Have a look at the documentation here http://simvascular.github.io/docsSimCar ... s-modeling and the svFSI input file guide here https://github.com/SimVascular/svFSI/bl ... master.inp.

Cheers,
Dave
