Hi,
I have a very simple and quick question regarding the configuratiuon of different variables in the solution vector(say v). assuming the variables to be velocity(vector) and pressure ,(u,p) ,then which of the following conventions are being used by Dolfin for a trianglular element? (subscripts stand for the velocity direction and superscripts stand for the node number)
1) v=[ {u_x^1, u_y^1, p^1} , {u_x^2, u_y^2, p^2} , {u_x^3, u_y^3, p^3}]
2) v=[ {u_x^1,u_x^2, u_x^3} , { u_y^1, u_y^2,u_y^3} , {p^1, p^2,p^3 } ]
Thanks,
Hatef
