C++ language has compiled the numerical simulation program of one-way fluid-structure coupling for filling pipeline, which has realized the process from model establishment, fluid calculation to structure analysis. The automation of the process ensures the accuracy of data transfer from fluid calculation to structural calculation. The correctness of the calculation results is verified by the program, and the one-way fluid-structure coupling numerical model is carried out for a section of)
