Hello guys,
If I want to make the BirdCarreau non-newtonian viscosity model dependent on time; how can i get this done? In other words, the following is the model: nuInf_ + (nu0_ - nuInf_) *pow(scalar(1) + sqr(k_*strainRate()), (n_ - 1.0)/2.0); Now if I need to change it as follows: nuInf_ + (nu0_ - nuInf_) *pow(scalar(1) + sqr(k_*strainRate()), (n_ - 1.0)/2.0) + 2*currentTime*nu0_; How can i get the value of currentTime? currentTime is the value of time at that particular instant. Please help me. Last edited by sanj; December 11, 2013 at 19:50. Reason: typo |

Hello,
could you please explain how you did to get the current time value? I need to set a time-dependent value of the viscosity. Thank you. David |
