N2 - This paper presents a workflow for implementing structural analysis on CubeSats using NX software. Four fundamental analyses, namely quasi-static, modal, random vibration, and buckling analyses, are demonstrated as a guide to simulate these tests for such CubeSats. AlAinSat-1 frame structure is used to apply the analyses using NX. The purpose of this paper is to guide beginners on how to use the software and perform such analyses. The methodology used in this study involves creating three types of FEM models that vary in the number of elements, conducting the four structural analyses, and evaluating the different techniques of the FEM models. To achieve accurate results using FEA, the element size of the meshing should be as small as possible. A convergence analysis shows that the results of models 2 and 3 are convergent. Therefore, the model 2 approach could be used to get acceptable results while reducing the computation time.
