Material Definition Input Generalized Fung

[PJtree23]

Hi,

I am trying to get a generalized fung material model working. So far my input file has yielded the error along the lines of: the material needs more lines to completely be defined. Here is what I have in my code so far:

**
**MATERIALS
**
*parameter
density=
c=
c1=
c2=
c3=
c4
c5=
c6=
*Material, name=MATERIAL-1
*density
<density>
*anisotropic hyperelastic, fung
<c>,<c1>, <c2>, <c3>, <c4>, <c5>

What am I doing wrong? Does anyone have dummy code of this material property definition? I am looking in doing 3D anisotropic material modeling.

thanks,

PJ
