CESE Compressible CFD Solver

The CESE solver is a com­press­ible flow solver based up­on the Con­ser­va­tion El­e­ment/­So­lu­tion El­e­ment (CE/­SE) method, orig­i­nal­ly pro­posed by Dr. Chang in  NASA Glenn Re­search Cen­ter. This method is a nov­el nu­mer­i­cal frame­work for con­ser­va­tion laws. It has many non-tra­di­tion­al fea­tures, in­clud­ing a uni­fied treat­ment of space and time, the in­tro­duc­tion of con­ser­va­tion el­e­ment (CE) and so­lu­tion el­e­ment (SE), and a nov­el shock cap­tur­ing strat­e­gy with­out us­ing a Rie­mann solver. To date, this method has been used to solve many dif­fer­ent types of flow prob­lems, such as det­o­na­tion waves, shock/­acoustic wave in­ter­ac­tion, cav­i­tat­ing flows, and chem­i­cal re­ac­tion flows. In LS-DY­NA, it has been ex­tend­ed to al­so solve flu­id-struc­ture in­ter­ac­tion prob­lems with the em­bed­ded (or im­mersed) bound­ary ap­proach or mov­ing (or fit­ting) mesh ap­proach.
