G0 in Prony series

[Wyb]

Good afternoon,

I want to create a viscoelastic material in Abaqus 6.9-2 CAE. Therefore I need to create a material in terms of density, elastic information (Young's modulus and Poisson's ratio) and viscoelastic information (In this case: Prony series). In the viscoelastic information section there's no where to put the Prony series' G0 term, only for gi's and taui's. So what should I do with it?

Thanks in advance for your reply!
