We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi Akshay,

thanks for your reply. As I mentioned before, my setup works well with small penetration. I have watched these videos already and have made sure to choose the contact and targets correctly and have also carefully chosen pinball radii for my model. As you can see in the following image, this is the original fairlead that I have modelled, and i have favourable results (model is 2-D axisymmetric to reduce computational effort).

But once i scale the seal to 110% (and adjusted the pinball radii), the solver fails due to high distortion of mesh, and only seems to work if i make the mesh extremely coarse, which seems wrong to me. Have increased loadsteps too, but didnt help. Only reducing mesh density helped.

Thanks,

Rohan
