Type Rectangle Circle

q (pressure)

Centre x (m)

Centre y (m)

Rotation θ (deg)

 

B (width, m)

L (length, m)

nx (divisions)

ny (divisions)

Radius a (m)

nr (radial divisions)

nθ (angular divisions)

Units arbitrary but must be consistent (e.g., q in Pa with m → σ_z in Pa).

Evaluation Point

x₀ (m)
