WEBINAR SUMMARY
In this 3-part, pre-recorded 40-minute webinar we will present how the automeshing enhancements now available in StressCheck v11.1 significantly aid in the rapid generation of penta- and hexa-dominant meshes for use in 3D multi-body contact applications. To realize these concepts in a practical setting, a 3D splice joint assembly will be constructed, analyzed and post-processed, with detailed commentary on each step in the workflow process.
