Hi all

I am on the moving frame of reference. I measure the Velocity on Z-direction and find the new height reached by my body.

Initial Height h0 = 41 meter
h=$h+($Vz*$TimeStep)

At every time step i gain new height and i want to get tat new height so tat i can implement to use it on Standard Atmosphere Density Distribution formula.

Thanks in Advance

Cheers
Gowhar

If i understand your question right - Field Sum Monitor of "$Vz*$TimeStep" with corresponding Report would help: you will get your additive value of "$h+($Vz*$TimeStep)".

"Field Sum Monitor" sum the values of "$Vz*$TimeStep" of all the cells of selected Region. I want to create a report and monitor the $hReport=$hReport+($Vz*$TimeStep) in the simulation and use the "$hReport" as input for Atmosphere.

I have attached the image of the Formula which i required to create and monitor
In this h(n+1) is current time step. h(n) is value at previous time step. I hope you understand
