    "abstract": "A computational fluid model is developed to study waves and instabilities. A\nnew technique involving initial perturbations in configuration space have been\nimplemented to excite the plasma waves; i.e. the perturbations acting similar\nto a random velocity distribution in particle in cell (PIC) codes. This forms a\nnew powerful tool for investigation of many waves arising in both thermal and\ncold plasmas and as such will allow investigation of problems demanding scales\nand resolution not yet possible by PIC codes. The model predicts Langmuir\nwaves, two stream instabilities, nonlinear wave-wave interaction, and the Debye\nscreening effects. The agreement between theory and simulation where analytic\nresults are available are excellent.",
