This article describes the way to simulate interaction of a highly intensive plasma flux (of the type common in
plasma focus devices) with materials. We apply 1D model of a target, assume a simple screening model of the
plate by evaporated material. Moving, rigid computational mesh and enthalpy picture applied allow convenient
and precise description of phase transitions in the sample. Intensive plasma bombardment causes destruction
of the sample surface by melting and evaporation. The stronger the flux, the more heat is used to evaporate
the sample and less is absorbed. The code purpose is to help extrapolate experimental plasma focus results to
thermonuclear fusion devices.
