I am trying to simulate bone growth in my spine model using a fortran code for the growth. If I use quadratic instead of linear elements in the hardware, will it result in convergence issues? Also, my next question is, whenever a maximum penetration error arises, is it because the contacts are not defined properly or there could be other reasons as well? Please let me know if the question is not clear and/or additional information needs to be told so that I can get proper suggestions regarding this.

Limits placed on how many workers can gather at a job site vary, but these physical distancing directives can be overcome with augmented and virtual reality (AR and VR) technology. AR and VR can transport key people to any job site, opening up the site and allowing more people to be on-site virtually, without requiring travel or risky physical interaction. Download Now
Data collection has always been crucial for the oil and gas industry, but it once required a team of multiple technicians carrying clipboards and tape measures to perform data recording in the field by hand.
