Calculate the temperature field of the 3D printing process using Abaqus. The cooling time is specified at the end of each layer. For the first two layers, the cooling duration is set to 15 seconds, and the simulation progresses without issues. Starting from the third layer, the cooling time is increased to 60 seconds; however, an error occurs immediately upon the initiation of the cooling process, causing the simulation to terminate. Below are the descriptions of the last two analysis steps as recorded in the .msg file. We kindly request your assistance in identifying the root cause of this issue. Thank you for your support！
