Abstract
The paper builds an algorithm to redefine the number of nodes when solving the 3 dimension frames problem by using finite element software to achieve high computing speed and mitigate memory requirements in the case of calculating large structural problems. With this numbering, the calculation time of those problems can be reduced by dozens or hundreds of times, the size of matrix arrays also reduces many times so that large problems can still be solved on the PC.
