The Application of ANSYS Multipoint Constraint on the Combination Modeling of SOLID-SHELL
The problem of the modeling connection of different units is encountered in engineering practice. Its reasonable proposals are that the modeling is discrete into the respective discrete three-dimensional solid elements for calculation. But different types of units’ degrees of freedom are not discontinuity，it will lead to significant deviation of calculated results and the actual. In the paper, the methods and characteristics of SOLID-SHELL unit with the application of ANSYS constraint equations method and the MPC law are discussed, and compared the shell - solid element with the whole solid element modeling combined the results, it draw a conclusion that MPC law is advantage in modeling of three-dimensional solid element and shell element.
