The finite element analysis process is generally pretreatment, calculation and post-processing. For preprocessing, especially for large and complex models, professional preprocessing software can be used, such as hypermesh, ansa, gambit, etc. Pre-processing files can be imported into abaqus for calculation and post-processing. There are also many tutorials about the basic operation of abaqus, such as the detailed explanation of abaqus finite element analysis examples of upstairs stones, and there are also many electronic tutorials on the Internet, which the landlord can check.
