CEL Variable "sstrnr"
Hi friends,
I am trying to calculate effective shear strain-rate (€bar) for a non-newtonian flow from shear strain-rate (€) variable of CFX; "sstrnr". The relaton is ; €bar = sqrt(2/3 €ij €ij) , ij are indexes However i dont know what "sstrnr" gives? A vector or a matrix? Can anyone help me Thanks, Serdar |
Re: CEL Variable "sstrnr"
Serdar,
The variable sstrnr is simply a scalar (modulus) representation of the shear strain rate tensor. If you want to calculate a quantity based on the tensor components, you'll need to extract velocity gradients via User Fortran in CFX. A description of the tensor and the sstrnr scalar is in the documentation. Regards, Johnson |
