    Hi Kostas,

    If you set the axes from curvature, you do not need to set the Axes property. I suspect that the error termination may not be related to this, but double check the FEBio input file to...

    Hi,

    I've never tried to do homogenization in 2D, but I suppose that if you fix all z degrees of freedom in both the RVE and the macro model, then that should be equivalent to a 2D plane-strain...

    Hi Kostas,

    Indeed, for tet meshes, the "local" option is not very useful. It uses the local node numbering to generate the axes, which is quite random for tet meshes. You should still be able to...

    Hi Lance,

    Glad to hear you decided to switch to FEBio :)

    We'll be happy to help convert this model to FEBio, although some aspects will be more difficult to address than others.

    Hi Andrew,

    Yes, please email me the model and I'd be happy to take a look (steve dot maas at utah dot edu).

    Hi Abha,

    FEBioStudio uses FEBio3 by default, but FEBioChem uses FEBio2 (at least if you are using the one downloaded from the website). If you have FEBio2 installed, you can make FEBioStudio use...

    Hi Kostas,

    The Fung-Orthotropic material indeed uses the local material axes. In the latest development build of FEBio Studio, you can set the material axes property, by clicking the material in...

    Hi Shamimur,

    We have seen the issue before, but unfortunately have not been able to resolve this. I only know that it is related to Qt, which is the UI engine we use, and that it probably is...

    The data range in the color bar is taken from the nodal values. However, if the data field you are looking at is not a nodal field (e.g. stress), then the nodal values are interpolated from the...

    Hi,

    In FEBio we only use isoparametric elements, which use the same interpolation functions for both the geometry and the solution. So, when you use higher order elements, the solution also uses...

    There are two approaches you can take:
    1) You can write the nodal displacements to a text file, directly from FEBio, using a user-specified formatting. Please check section...

    Hi,

    FEBio only does 3D. (I think there was a 2D fluid formulation implemented for testing the initial fluid solver, but I'm not sure what the status of that is.)

    That said, you can usually...
