In the realm of supramolecular synthesis, the construction of rack, ladder, and grid architectures represents a particular case of self-assembly, which relies on the three basic levels of operation of a programmed supramolecular system recognition (selective interaction of complementary components) orientation (building up the stmcture through the con ect spatial disposition of the components) and termination, that is, the formation of the desired discrete supramolecular entity. "... 

Outcomes of the solvers are analyzed by using the postprocessors, the collection of tools that, in general, allows detailed visualization of the computational domain and the grid architecture, editing and refining the 2D/three-dunensional (3D) plots of the distributions of dependent variables (e.g., velocity, temperature, species concentration) along the computational domain and displaying time-variable results in animated forms. 

The design and synthesis of supramolecular architectures with parallel control over shape and dimensions is a challenging task in current organic chemistry [13, 14], The information stored at a molecular level plays a key role in the process of self-assembly. Recent examples of nanoscopic supramolecular complexes from outside the dendrimer held include hydrogen-bonded rosettes [15,16], polymers [17], sandwiches [18, 19] and other complexes [20-22], helicates [23], grids [24], mushrooms [25], capsules [26] and spheres [27].
