  1. D-Compress

    09 Apr 2015 | Contributor(s): Alain Burgisser, Marina Alletti, Bruno Scaillet

    D-Compress computes the gas and melt volatile composition of five element sets in magmatic systems (O–H, S–O–H, C–S–O–H, C–S–O–H–Fe, and C–O–H). It has been calibrated so as to simulate the volatiles coexisting with three...

    A 2D non linear diffusion code is by Mattia de' Michieli Vitturi (Istituto Nazionale di Geofisica e Vulcanologia, Sezione di Pisa).This code solve for the nonlinear diffusion problem dh/dt = div( f(h) grad(h) )wheref(h) = k * ( 1 + ( max_nlc -1 ) * ( |grad(h)| / S_c )^n )k is...

  3. PlumeMoM

    27 Mar 2015 | Contributor(s): Mattia de\' Michieli Vitturi

    PlumeMoM is a numerical code for the steady-state plume model, describing the rise in the atmosphere of a mixture of gas and volcanic ash during an eruption. The system of equation is formally the same of that presented in Barsotti et al. 2008, i.e. the equations we formulate describe the same...
