I’m doing an incompressible flow sim called “1 Moderate Incompressible (Average Wind Speed Crosswinds)”. I’m confused about some of the results that came from the forces calculations. https://www.simscale.com/workbench/?pid=1777385904090276987&mi=spec%3Ae30e51f9-5a5b-4972-a064-682d18e230b9%2Cservice%3ASIMULATION%2Cstrategy%3A6
So I set the sim to calculate the forces on the entirety of the upper and lower surface. Then, I did the same calculation but where the forces were calculated for each face on the body. When I compare the results, the “total surface force” is about equal to the force calculated on a single face. So I’m confused as my expectation was that the sum of the faces would add up to that of the total surface.
Thank you for your help
