using forces for geting drag and lift force magnitude?
Hi guys,

I am looking for the drag and lift forces on solar panel in a wind tunnel.

I've been looking at postprocessing forces but I couldn't get it to work.
I put forces function on my controlDict, do i need to change any other files?

What are the command use to find these forces? i've been using foamCalc but it keep comming with


Create time

Create mesh for time =0

No P

No P

No P

What do I miss? :confused:

any pointers would be appreciated

It seems that the field P (pressure?) is not saved at each of the time instants. Check that the required fields are written to the folder.
