hi!

i have done a simulation with water inside of a tank, and a excited it with a aceleration by an equation in expressions in cfx-pre.

I want to know how in cfx-pre how i can introduce an aceleration by an file created by me .

thanks

Hi!!!

In my simulation in CFX-POST /tools/Function Calculator

i choose witch time step i want and i can calculate for example

Function:Force Location:Left Direction Global | y Fluid:Water Result: ... [N]

i need to export wall the forces along the witch time step

but if i go to :File/export File: Type:Generic locations:left Cord Frame :Global Unit System:SI Boudary vals:

Select Variable:Force

The result of the force is very different.

why?' What i am doing wrong?

Thanks a lot.
