Well, this seems simple enough. The only parameters to set are the boundary conditions, and yet I somehow managed to screw it up. I want to swell spheres in NaCl. I set initial conditions and effective pressure on the outer nodes of this 1/8 sphere, but the energy and residuals are nan, or alternatively negative Jacobian throws error. How do I set the initial concentration inside the sphere, isn't that the fixed charge parameter in triphasic material? Anyhow, this is my first FEBio file, so it should be easy to fix. Please see Gel.prv file attached. Any suggestions welcome.
