The new DesignSPhysics-GUI is awesome !
create the case in 3D
define movement of one or more bodies
define physical and solver parameters (tons of options)
press „Change 3D/2D“ button ==> 2D case is generated, speeds up simulation
export fluid and body motion as vtk-series for paraview
generate csv-files for plotting forces and motion (x,y,z,pitch,roll,yaw) in excel
measure pressure at every point you want
a.s.o...all in one GUI
Thumbs up to the developer, great job!
