Hi, Folks -- Is there a function that gives the reference coordinates for each node of a (Lagrange) element?
The reason I ask is that I have a variable, say x(X), restricted to a particular side of a particular element for which I would like to identify any positions at which x(X0) = x0. If any such positions exist, I then need to evaluate some other field variables at those locations, which I can easily accomplish if I know the reference coordinates corresponding to position X0, but not if I only know the value(s) of X0. Doing this in general seems like it could be a real mess, but for lower order Lagrange elements it does not seem too bad. However, I think that I need to know the reference coordinates of the nodes, and I have been unable to find an API that seems to give access to these values. (It is my impression that functions such as Elem::point() give the current coordinates of the node, not the reference coordinates.) Also, I realize this probably seems like kind of a bizarre thing to be computing, but does there happen to be any existing code in libMesh that could be adapted to do this kind of thing? :-) Thanks! -- Boyce ------------------------------------------------------------------------------ Benefiting from Server Virtualization: Beyond Initial Workload Consolidation -- Increasing the use of server virtualization is a top priority.Virtualization can reduce costs, simplify management, and improve application availability and disaster protection.
