gravity should be replaced with body force. Current implementation only allows us to apply force in y-direction

turtleFSI/turtleFSI/modules/solid.py

Lines 63 to 66 in c52ebc2

    
           if gravity is not None and mesh.geometry().dim() == 2: 
        
               F_solid_linear -= inner(Constant((0, -gravity * rho_s)), psi)*dx_s[solid_region]  
        
           elif gravity is not None and mesh.geometry().dim() == 3: 
        
               F_solid_linear -= inner(Constant((0, -gravity * rho_s,0)), psi)*dx_s[solid_region]

Oasis can be used as a reference point for the body force.
