Default implementation of Bigham viscosity by UDF
Posts: n/a

In order to implement Bingham rheology (with yield stress) I have to implement the dynamic viscosity as function of the rate of strain. The problem is that it should take into account both the normal and shear strain. Does someone know if this can be done by means of UDFs, and how? Or if someone has another idea about how to implement Bigham rheology I would love to hear it...

Thanks a lot in advance! Cheers, Bob
