Markus Werle is a mechanical engineer trying to finish his doctoral thesis in ComputationalFluidDynamics? at RWTH Aachen (University of Technology Aachen, Germany).
You can reach him via mail (numerical.simulation@web.de).
Markus has developed a new method which allows to apply C++ ExpressionTemplate technique to any set of classes without modification of their code just by using a header library and writing additional code.
