Pull request overview

Updates the C++ “Getting Started” quick-start snippet (transport1D.cpp) so it matches the working MOLE C++ example and compiles as a self-contained program.

Changes:

• Adds missing simulation parameters (m, iter, dt, dis, vel, R, C0) to eliminate undeclared-variable compile errors.
• Adds initial conditions and time-stepping details (including dispersion/retardation scaling and a right boundary condition) to make the snippet runnable.
