    how to get the accurate node coordinate?

  dear sir:

      as shown in the manual that the flux calculated through the 'fluid flux analyzer' is not exact flux values, i get two questions about this flux: (1) whether the error between the this flux and the exact flux is bigger or not ?
(2) if the error is bigger, how to calculate the exact fluid flux?

    thanks

thanks a lot

 
  how to give the possible overflow boundary?

  and how to get the accurate coordinate of the node, if use the constraint conditions to give the overflow boundary?

thank you very much

as said in the tutorials: border is a mouse-controlled input of boundary conditions along the boundaries of the model. A constant value can be set, or, by setting a start and an end value, a linear interpolation along the boundary is performed.
i would like to ask a help for the realization of this step, how to set the start and end value?
thanks
