      I wanted to do a static structural analysis with TPU material (set as hyperelastic moonley rivlin 5 parameter). However, it keeps telling me that element is highly distorted and ansys stops the calculation. I tried to use KEYOPT 6 and 16 but it does not work. My mesh has been set to linear type and the mesh type is nonlinear mechanical. Is there a solution to this? I attach the image of the model. In this case, I wanted to pull the 3 bars downward until the top of the geometry is close to the bottom one. Thank you in advance.
