How can I extract the drag and lift coefficient?

Javier Mediavilla Hidalgo

 Hi!!, I already have the simulation finished, with its '.log ' file generated, and I need to know how I can know the drag and lift coefficient using HyperMesh CFD 2023 or HyperGraph. Can someone tell me how to do it? Thank you so much
All the best.

You should have surface output sets for the body in question.  The surface integrated traction components will be the force components - from which you can derive the coefficients based on your reference area, reference velocity, etc.

To plot:
https://help.altair.com/hwdesktop/cfd/topics/pre_processing/solution/plot_run_time_data_t.htm#plot_run_time_data_t

The traction integrations (forces) will be under the 'Integrated Surface Output' > Forces and Moments section

To extract data to a table:

This brings up a GUI to select which data to extract.
