Hi Gibbon community,
I have some questions about the interaction between Gibbon and FEBio
Can you help me please
Is it possible to assign a load curve to a parameter that is external from the FEb struct ?

@danielcpnkimo
Hi, I've tried to test the "DEMO_febio_0015_cube_fibers_transiso"
But when I change the "alpha" from 1/3 to 0, stress-stretch curve doesn't change at all.
Is there anything wrong with this Gibbon model?

This is the result when alpha = (1/2)*pi;

@danielcpnkimo
and this is the result when alpha = 0

There is no differences between the two results, which isn't make sence at all for the anisotropy result from the present of fibers.
How can I fix this?

@danielcpnkimo thanks for your post. I answered on #27 let me know how you get on.
@amine_bohi_twitter thanks for your post. Sorry for the late reply. Can you elaborate on your question? A quick answer is, yes you can code anything you like, i.e. any FEBio functionality can be coded in GIBBON.

The problem is solved after I changed to MATLAB R2018a and FEBio 2.7.1 and the latest Gibbon codes. Thanks for your reply. Below are my current result.

Is there a way for Gibbon code to have feature like I can assign the direction and material properties of of each fiber in Gibbon? I have a matrix of all the fiber direction in the order of their element number.

Hey guys, there seems to be various problems with the installer and/or code base centred around 1. 'Undefined function 'contains' for input arguments of type 'cell' and 2. Error using builddocsearchdb (line 29)
There is no installed product with this help location.
Documentation that is not associated with a product will not be displayed in the help browser.

Error in addHelpSearch (line 8)

@Kevin-Mattheus-Moerman
Thanks I'll check this out
Contains is a new function in MATLAB 2018

Ah I see, trying to run in 2016a at the moment so I'll see if I can update versions. Thanks for your quick reply!

I have found your lattice generating code very helpful with the work I am trying to achieve, but I have found that where the struts are intersecting, gaps are being created (element2lattice). I have shown here a slice plot in the z planee PostView results

Thank you for making this extensive code collection available for us. Im currently trying to fix this myself but after a week I have not been able to make significant progress. I have even tried reprogramming this from scratch and although I can generate the structure and apply boundary conditions, I find that my main obstacle is FEBio outputting errors containing "Did you use the right node numbering?"

@Kevin-Mattheus-Moerman
I can help. Can you send me the setting that you use for element2lattice? Perhaps also send me more pictures of the problem. kevin.moerman@gmail.com
