A system and a method for analyzing and simulating a die swell and flow profile in polymer melt extrusion through a die. The system includes a mesh generator to generate a computational mesh; a pre-processor to obtain die parameters, boundary conditions, polymer melt parameters including rheological characterization and constitutive equations and to generate an input file; a simulator to receive the input file from the pre-processor and process the input data to simulate die swell; a mesh corrector means to analyze the die swell obtained from the simulator and to correct the motion of the computational mesh and polymer melt to converge the die swell; a post-processor to visualize the die swell and flow profiles for the polymer melt; and a database means to store the die swell corresponding to the die, mesh and polymer melt parameters.
