When evaluating wave forces acting upon a structure, why is only the normal component of the stress tensor taken into account in determining the net force? Why are shear stresses ignored?

Shear stress is also included, see the second term for calculating Fx in force_force.cpp:

HTML Code:
Fx += -(pval)*A*nx
                       + density*viscosity*A*(du*ny+du*nz);
