time variable in cfd post

r_abdollahi70 · June 24, 2017, 05:40

hi
I want to define time variable in expressions of cfd-post. my variable is wall shear stress and my result is transient. I want to compute counter of oscillatory shear index (osi). for this I need to compute sum of wall shear stress in all node separately.
my question is!
how define sum wall shear stress in all time or specific time steps?

Please define this statement properly. Mathematics requires precision, so please define exactly what you mean.
