This paper introduces the modeling and FEM simulation of FDSC Multi-Point Forming based on ABAQUS. Python is used as programming languages to secondary develop the software and to establish a simulation platform. An additional module was developed for the automatic modeling with the functions of: (a) basic parameters input such as material performance, plate size (b) rapid assembly of MPF punches and sheet automatically (c)automatic definition of the analytical step and the output of variables and (d)automatic definition of interaction conditions, loading and meshing. The additional module developed was used to simulate the forming of different curved surfaces to verify its efficiency and accuracy. The results showed that the pre-treatment modeling for FDSC MPF can be established automatically and quickly. The simulation can be accomplished within a receivable speed in ABAQUS. Future more, experimental deformations were carried out and the simulating results are compared with that of experiment. Comparison shows a good consistency between the experimental data and simulation data.
