Let's revise it until it's simple enough. The point about the redesign is to make it simple. > I just want a function in Coefficient that takes a point and a cell > and evaluates the function.We have Coefficient::eval(double*, > Data&), but the necessary functions to constract Data were private. The point with Data is to keep it simple, in particular to avoid having many different versions of eval, one when the cell is available, when it's not, when the facet is available etc etc. So there are two versions: one with just the point x and another one that should cover the rest. > Also, if one calls Coefficient::evaluate(....), the coordinate are > updated in the Data object (inside Coefficient::evaluate(.)), but > not the cell. That's a bug. It should be updated. It should fill out the data with all information it has: the cell and the coordinates. I'll fix it. More data may already have been filled into Data, like the current facet if it's known during assembly (set at the time of calling the restrict function). -- Anders
