Hello,

Check the following video on how to handle element distortion error for hyperelastic materials (with the majority of guidelines applicable to other materials as well):

Hello, this message pops up when i run the analysis to define the timestep of the plastic collapse load on a thin strip with an elliptical hole on ansys mechanical apdl. i checked the mesh and there was no error shown by the software. i try to increase the number of substeps or decrease the timestep size but still nothing. I am not sure if there is any problem with the design or shape of the elliptical hole as i couldn’t find a command for the design of an ellipse(major axis is 20mm and minor axis is 10mm) located at the center of the thin strip.
