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

"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
