Hi Dave,

If I'm not mistaken, this appears to be implemented only for the HO model, and not for the HGO model.

Thanks,
Aditya

Hello, The material model described in Gasser et al (2006) states that the collagen fibers do not support any compression and would buckle. Therefore, the anisotropic part of the HGO model only contributes to the strain energy if the strain in the direction of a_0_i is positive. strain.png https://r...

Hi, I am trying to perform an FSI simulation using svFSI for an artery inside a tissue. The case is linked here: https://drive.google.com/file/d/188nV_wYz72tLr1iwmkf0QcTvUdS9zFaZ/view?usp=sharing There are three domains, blood, artery wall, and tissue, (as shown in the figure). domains.png In my fir...

Hi, I am restarting a svFSI simulation that had stopped due to cluster time out issues. After restarting it, I get this error: stamp.png https://drive.google.com/file/d/12yb6E8fe9Y9rXq4zaD8dGIvOob6oLTd8/view?usp=sharing Can you please help me tackle this error? I have attached my files just in case ...

I see, thanks for sharing.

Best,
Aditya

Hi Hunor, I managed to fix this issue by applying a stiffness value using the external tissue support boundary condition (Robin BC) in simvascular. approx. 1e3 in SI units The issue I believe is that because we are fixing two ends of a long cylinder, some kind of vibration/oscillatory behavior is ge...

Hi, In the svFI_master.inp file, it says a spatially varying load can be applied. intetl.PNG I'm assuming this means that I can apply pressure at a specific location of my choosing. Is there an example or tutorial on how to create the VTP file where I would like to apply the pressure? Thanks Aditya

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 . How do I provide the fiber direction for the following case? fiber.png The angle gamma I would like to use would be: 49.98 Degrees. PS. The case is from the o...

I see,

Thanks for the info Dave.

Hi, I am trying to see whether I could modify the svFSI code to include the Fung's model for the artery, as this appears to be a common model using to describe the artery solid mechanics. I wanted to evaluate the potential effort in adding this model? Logically thinking, it seems it would not be too...
