Applying Non-Uniform Distributed Forces/Pressures in Abaqus

 I am working on a problem involving wind-tunnel testing of a component. Basically, the component has numerous pressure tappings on its surface to measure the pressure in the wind tunnel. I am required to apply these pressure measurements into the Abaqus model. I am looking for some suggestions as to how best to accomplish this. Basically, the output from the pressure tappings looks like this (I moitted some details...):

SN    X    Y    Z    CP    Local Pressure (Nm-2)    NX    NY    NZ    Wetted Area (m2)    Normal Force (N)    Fx    Fy    Fz

 1    0.25    0.0065    -0.0827    0.793    58664.636    0.3144    -0.0745    0.9464    8.87740E-07    5.208E-02    1.801E-02    -3.878E-03    5.914E-02

 BTW, there are>1000 data points.

My first guess would be to try and somehow input the forces (Fx Fy Fz) into the model using subroutine, but then I thought maybe the pressure data would be more efficient.

Questions:

 1. Which is easier to input into the FEA model? Pressure or Forces?

2. How can I discretize the mesh such that the forces can be loaded exactly into its corresponding coordinates?

3. If pressure is used, can I curve fit the pressure data to derive an analytical field to serve as the distribution?How does wetted area come into the picture?

 

Thanks!
