Adding Fung's model to svFSI

[Aditya Bantwal]

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 difficult as I am assuming all I would have to do is add the strain energy density function similar to how the other material models are implemented in svFSI.

Would this be a trivial task? It would be great if you could point me to the files that would need to be modified in svFSI if I had decided to include this material model.

Thanks,
Aditya

Hi Aditya,

Adding a new material model will not be trivial, several parts of the code will need to be modified, but it is doable if you have Fortran programming experience.

I looked through the code a bit and seen that the following code needs to be changed

Code: Select all

Add new type of constitutive model in CONSTS.f

Update READMATMODEL() procedure in READFILES.f 

Update GETPK2CC() or GETPK2CC() in MATMODELS.f 

There may be other places in the code that might need to be changed, you will need to figure that out.

Cheers,
Dave

I see,

Thanks for the info Dave.
