Development Status of Beam Dynamics Software APES for CEPC

The physical design and research work of China Electron Positron Collider (CEPC) is an unprecedented challenge in the field of international accelerator collider. In the simulation research, many physical phenomena must be considered, including large Piwinski angle, crab waist colliding, strong nonlinear effect, energy sawtooth, beam-beam, etc. To address this challenge, a software project APES is proposed in 2021. And this project received support from the IHEP innovative fund in 2022. The progress and future plans of APES project will be introduced in the poster.
