Interpolation methods in ANSYS Mechanical
I am in the process of modelling a full 3D tyre but have found that my model might be undergoing volumetric locking. I have read that by reducing the interpolation method that the effect that volumetric locking has on ones results can reduce. In my results the excessive non-realistic stiffness in the figure below, I believe, illustrates this phenomenon.
I am using ANSYS Mechanical, and saw that at the interpolation method my simulation is using; Mechanical APDL.
I have read this discussion https://forum.ansys.com/discussion/4342/interpolation-methods, but am unsure how to change the interpolation method as the box does not have a drop down option (see image above).
The following are my Analysis Settings:
Thank you in advance
