Hello everyone, I am currently working on a coupling problem of three-dimensional flexible plate flow. I am using Abaquse to draw the structural mesh and write the inp execution file for Calculus. However, when I write other cases in the same way, the problem shown in the following picture does not occur, but it appears at this moment, and I cannot understand or know how to solve it. I am certain that the dimensions of the fluid solid interface are matched, as the structure and fluid mesh were drawn separately using a single model. As with the information output from the terminal, I don’t understand the next steps and don’t know how to proceed. Please help me, thank you very much.
