K and epsion

ivanyao · August 18, 2008, 21:14

hi,
I am doing a simulation about the wind pressure on the building.And the k and epsion is not the certain value.
k(z)=1.2*[I(z)*u(z)]^2,epsion=(c^0.75)*[k(z)^1.5]/KL.and the u(z)=6.97*z^0.16,
I(z),c,K,L are the certain value.z is the height of the building.how can i write the k file and the epsion file in the "0" file.

Hi weihong,

Utility funkySetFields could be suitable for that purpose.

I think that's really can work,but i don't understand how to do even i have gone through all the step.would you give me a hint?
