How to measure force at each time step

ToPFouraces · August 13, 2017, 01:44

Hi,

I would like to record the total force on a wall (caused by fluid impacting on the wall) at each timestep of the simulation, and either plot or write the results to a file.

Does anyone know how I could go about this?

report force / write to file
OR:
MONITORS/DRAG(OR LIFT) PLOT AND WRITE ACTIVETED

I have tried report force / write to file, but this only gives a single force value for the current simulation flow time.

Would I have to stop the simulation every time step and complete a force report?

Yes u r right
you can plot force under monitor, when solution is completed, press write at
the plot page then write force data to file，you will get force history.
