Fluidic Force Output

Post by Will01 »

Does anyone know how to output the Fluidic Force in a file? like .dat
I can see the calculated forces in the solver output, but not in any output file, like *.ep or *.vtu, I tried to set the SaveScalar to save it, but failed, please let me know if you can help on this. thanks!

ForceCompute: -------------------------------------
ForceCompute: Forces on Boundary bc 4
ForceCompute: Fluidic Force: 1.740868E+00 -7.361558E-03 0.000000E+00
ForceCompute: Resultant Force: 1.740884E+00
ForceCompute: Contact Area: 4.000000E+00


Does anyone know how to output those results in a result file? like .csv. I can see this in the solver not any output file.

The solution is as follows, please note it's important to set this solver at the lowest priority and it will output the cd and cl with time. FluidForce 4 is relate to your BC number.


Solver 1
Equation = SaveScalars
Variable 2 = FluidForce 4
Filename = FluidicForces.dat
Variable 1 = Time
Procedure = "SaveData" "SaveScalars"
Exec Solver = After Timestep
End

Boundary Condition 4
Target Boundaries(1) = 4
Name = "Walls"
Velocity 1 = 0
Velocity 2 = 0
Save Scalars = True
Calculate Fluidic Force = True
End
