How can I improve my hyperelastic model boundary conditions to improve and sucessfully run my model?

I am trying to complete a quasi-static and impact simulation (compression) on a lattice structure using static structural. The material is a hyperelastic polymer represented by the Yeoh model in the engineering data tab. I am running into issues of elements becoming highly distorted as well as issues with boundary conditions. Is there any suggestions for fixing the simulation? So far I have tried fixed support and displacement as my method of compression as well as relative displacements and have had no luck. Any suggestions appreaciated! @peteroznewman
