Greetings!
I'm working on simulation of arteries from in vivo imaging. For this I plan to use the prestrain module.
I'm trying to work in two steps, first imposing an approximate prestrain field from theory and adapt it to be compatible with the actual geometry. For this I'm using the prestrain elastic material and the prestrain constrain using first a simple uncoupled Mooney-Rivlin model.
Latter I want to use that prestrain as initial condition for the artery inflation process. For this I included an inflation time step and the prestrain initial condition with init and reset parameters set to 1.
Nevertheless I'm not getting my files to run. I'm using FEBio 2.9 version. I'm attaching the prestrain constraint file (febpre_strain.feb) and the prestrain initial condition files (febpre_strain_ic.feb).
I'm out of ideas and I checked the syntax along the files. Could anyone please give them a look and tell what could be the problem? I'm clueless at this stage.
Best regards,
Johane Bracamonte
