How to define visco-hyperelastic material model in Workbench?

      In a viscoelastic material model, there is an elastic component which is used in combination with Prony series, which defines the viscous component. By default, the linear isotropic elastic model is used for the elastic component, however, a hyperelastic model can be used too, which is nothing but the viscohyperelastic model. In order to do this, define a hyperelastic model, then insert Prony series. Note that introducing Prony series will disable the hyperelastic model and introduces linear elastic component. This is just a minor limitation with the interface, one can manually disable the linear elastic component and enable the hyperelastic component.
