“…The SNeuT simulation code uses the CVODE package, an open source software package which is part of Lawrence Livermore National Laboratory's SUNDIALS suite. SNeuT is a fork of the MITNS plasma transport code [21]. Authors are thankful to Eric Emdee, Mike Mlodik, and Jace Waybright for fruitful discussions, and to Ian Ochs for fruitful discussions and for involvement in code development.…”

When a gas in an externally imposed potential field is compressed, temperature gradients appear. This has been called the piezothermal effect. It is possible to analytically calculate the time-dependent behavior of the piezothermal effect using a linearized fluid model. Quantitative differences between the fluid-model results and previous numerical calculations can be explained by the effects of viscosity and heat conductivity. The fluid model casts the piezothermal effect as a spectrum of buoyancy oscillations, which yields new physical insights into the effect.

“…In contrast to neutral gas, however, magnetized multi-ion species plasma features multiple heating mechanisms, so the temperature profile can be tailored by modifying the exter-nal potential and plasma parameters. These properties of magnetized multi-ion-species plasma were successfully observed with the code MITNS [7].…”

Stratification due to ion-ion friction in a magnetized multiple-ion species plasma is shown to be accompanied by a heat pump effect, identified for the first time here, transferring heat from one ion species to another as well as from one region of space to another. The heat pump is produced via newly identified heating mechanisms associated with charge incompressibility and the Ettingshausen effect. Besides their academic interest, these new effects may have useful applications to plasma technologies that involve rotation or compression.
