Hi all,
Below is my inputs in CFX-Pre, how do I define the period of the motion as Ansys CFX won't allow the expression Period because it is already an object.
Thanks in advance
LIBRARY:
CEL:
&replace EXPRESSIONS:
DownWHeight = 0.12 [m]
DownWVF = step((x-UpWLength)/1[m])*step((DownWHeight-y)/1[m])
OverallAirVF = 1-OverallWVF
OverallWVF = UpWVF+DownWVF
UpWHeight = 0.12 [m]
UpWLength = 1.2 [m]
UpWVF = step((UpWLength-x)/1[m])*step((UpWHeight-y)/1[m])
XAmplitude = 0.06 [m]
XFrequency = 1/Period
XOmega = 2*pi*XFrequency
XSway = -XAmplitude*(XOmega^2)*sin(XOmega*t)
YSway = -9.8 [m s^-2]
END
END
END

If "Period" is a reserved variable name then just use another one. Or have I misunderstood your question?

[adamdogster]

so what other name do I put so CFX understands that i want to define the period of the motion?

I am very confused by your question. If you want the period as 5[s] then you can define it with slkjghsa = 5[s], and use it with XFrequency = 1/slkjghsa

If you don't like the variable name slkjghsa you can define it as anything you like - except the reserved variable names.

Thanks for your answer

Glenn, slkjghsa is bad name, hrrrrrqnfarpombxl is much better.
