Active contraction in Transversely Isotropic Mooney-Rivlin


I am trying to use the active contraction in the Transversely Isotropic Mooney-Rivlin model on a Mac. I tried running the test suite model (fi01.feb) in FEBio versions 2.4 and 2.5, but nothing happens in the model (No force acting on system). When I run the model using v 2.3, the model does what it's supposed to do (the bar contracts). My colleague ran the test suite model on a Linux using v. 2.4.3, so this seems to be a Mac issue affecting v.2.4 and 2.5 releases.

Thank you,

Hi Kyoko,

I haven't been able to reproduce this bug on 2.4.2, 2.5.0 or 2.6.3 on the Mac. All these versions produce a contraction in this model (fi01.feb). As far as our records show, fi01.feb was last modified on August 14, 2015, so I am guessing that you are using the latest version.

Would you be able to post (or email me) another test problem that seems to fail?

Hi Kyoko,

Thanks for emailing me the file you used. That file is an older version, which has one difference against the current file in the test suite:

The old file uses
<active_contraction lc="1">

The latest test suite file uses
<ascl lc="1">1</ascl>

If you make that change to your file it should run properly (please let me know otherwise).
