ABSTRACT
Analysis is presented that shows that the paper by Ruskov, Ney, and Rahman (Phys. Plas. 28, 112701, 2021) gives incorrect physical interpretations to liner-on-plasma computational results and has mathematical deficiencies in the computational approach. The analysis also confirms a previous result: Mach2 calculations of the so-called staged z-pinch artificially inject energy that leads to the incorrect conclusion that the calculations should reach fusion temperatures.
