Videos demonstrating simulations of Radical Induced Cationic Frontal Polymerisation in a 2D finite difference model composed of a insulating mould surrounding a cavity. The following acronyms are used in the filenames: PP: Pure polymer (no fillers) GF: Glass fibre reinforced polymer vf: Volume fraction (followed by quantity) w: Width of one foam mould halve in mm T0: Initial set temperature of the system trig: Trigger time in s
