Abstract： Ansys and Nastran solvers are used to solve the same solar battery array model，and the methods of model creation，mesh characteristic inspection and element atribute setting are introduced in detail. Through modal analysis and comparison of calculation results， the correctness of parameter settings of the same model under different solvers is verified，which provides support for the transformation of finite element model format，and has certain guiding significance.

Key words： finite element model； composite material； hinge； mesh check ； property setting
