Using 94Quad element for dry sand?

Post by Rubinsa » Mon Feb 13, 2023 3:29 am

Hello, Is Nine Four Quad element only useful for saturated soil? Can I use it for Dry sand? I used Quad element so far, but I want to use Nine-noded element for better results and more precise shape function.

Thank you for your help!

It should work with any constitutive model, just like the quad element

Thank you for your response!
Since the Nine-Four quad up element has some pore pressure nodes, how can we define those nodes to be dry soil ? The only thing we can change is the fixity for pwp which means opening and closing the drainage. How can we specify that there is no water?
