Dear Davide I'm working on a large MOF too. There are 8 "molecular" units in my cristallographic unit cell, 180 atoms for each molecule, so *no way* to simulate the whole crystal cell. But learning from quantum chemists (;-)) I've embedded a single unit in a cubic cell and I've used the

Dear Iurii Thanks for answering 1) MOF is a metal organic framework, namely an hybrid crystalline material alternating inorganic node with organic ligand 2) as you can imagine no it is not a molecule. If the problem is due to the cell parameters being not orthorhombic I might consider to run
