Employing our developed particle-based simulation models of viscous fluid dynamics and heat transfer, this method realizes the visual features of lava flows: lava flows broaden like a fan form; the viscosity of lava changes according to its temperature; cooled lava solidifies into crust or new ground; the color of lava changes according to its temperature; crust is dark; lava of high temperature run out by breaking crust; etc.
