The primary phase is the mixture of reactant gases, and the secondary phase is the material that we want to melt at a certain temperature. No interphase reactions are activated. Wall surface reaction is selected and happened on a porous zone when the mixture diffused from the boundary to the surface of the porous zone. The phase 2 which is right on top of the porous zone will be melted while temperature increasing. No UDFs are used. The boundary conditions, initial conditions and the properties of all the materials are copied from the papers.<\/p>\n<p><\/p>\n<p class=\"MsoNormal\" style=\"box-sizing: border-box; margin: 0px 0px 10px; font-size: 15px; overflow-x: hidden; font-family: 'Open Sans', Arial, Helvetica, sans-serif; text-indent: 21pt;\"><span lang=\"EN-US\" style=\"box-sizing: border-box;\">However, the problem happened right after clicking &ldquo;calculation&rdquo; if the simulation is running under the parallel processing.
