Stills from YouTube video of buried roadside explosive
As one of four institutions collaborating with the University of Colorado — Boulder, the CSM group in the Department of Mechanical Engineering at the University of Utah, will be developing constitutive models for soils, as well as full-scale simulation capabilities in Uintah to predict blast and ejecta from shallow buried explosives (such as roadside improvised explosive devices). The $1.1M slated for CSM work presumes the project will last 5 years. For more information, see the University of Colorado’s press release.

According to wave propagation in soil models, is it beneficial to use meshfree methods or isogeometric analysis?
Actually, I utilized NEM (Natural Element Method) in solving seepage problems (diffusion issues) and found out good results. But I am confused about wave propagation problems. I was wondering if you could guide me
Thank you
