Considering time value in the boundary profile?
I am trying to simulate fluctated wind pressure of building using cfx10.First, I have used Matlab software to generate the time history of wind velocity;then, I want to add the time history of wind velocity to the inlet boundary condition by using the boundary profile of cfx10 .To this step, the question is how can I reach this target.
List the format what I have tried and failed: [Name] My Boundary [Spatial Fields] x, y , z... [Data] x[m],y[m],z[m],t[s],Velocity u[ms^-1] 1,2,1,0,1 1,2,1,0.5,2 1,2,1,1.5,0.9 ...... Need your help,thank you! |
Re: Considering time value in the boundary profile
Hi,
I guess you need to setup a CEL Expression with something like Function(x,y,z,t,u)in CFX, where x,y,z,t are input and u output data. Create a User Function where to read the data of your txt file and send the data via Function(x,y,z,t,u) back to the boundary condition. I think there are some examples in the CFX manual for CEL or User Junction Box which can you help further. TobiasZ |

TobiasZ,thank you for your help! I has obtained the real results with using the user cel function.
