An in-depth understanding on laser plasma interactions (LPI) is required when pursuing better ICF implosion performances. Fluid-like models usually require less computational resource and have controllable noise levels, compared with particle-in-cell (PIC) kinetic models. I will introduce our ongoing FLAME (FLuid code of lAser-plasMa instabilitiEs) project and a newly developed code FLAME-MD (Multi-Dimensional) with efficient parallel techniques employed. 3D FLAME-MD Simulations are performed for two plasmon decay (TPD) instabilities in three dimensions (3D) with parameters relevant to ICF. It is shown that TPD growths are much slower with a circular polarized (CP) laser, indicating a likely advantage using CP lasers as the ICF driver.
