[soln-plugin-fluidforce-name]

Periodically integrates the pressure and viscous stress on the boundary labelled name and writes out the resulting force and moment (if requested) vectors to a CSV file. Parameterised with

1. nsteps --- integrate every nsteps:

   int

2. file --- output file path; should the file already exist it will be appended to:

   string

3. header --- if to output a header row or not:

   boolean

4. morigin --- origin used to compute moments (optional):

   (x, y, [z])

5. quad-deg-{etype} --- degree of quadrature rule for fluid force integration, optionally this can be specified for different element types:

   int

6. quad-pts-{etype} --- name of quadrature rule (optional):

   string

Example:

[soln-plugin-fluidforce-wing]
nsteps = 10
file = wing-forces.csv
header = true
quad-deg = 6
morigin = (0.0, 0.0, 0.5)
