Material Parameters

1. UCSDSAND3

*MATERIAL,NAME=UCSDSAND3
*USER MATERIAL,CONSTANTS=24

2. UCSDCLAY

*Material, Name=UCSDCLAY
*USER MATERIAL,CONSTANTS=8,Type=Mechanical

Note: To apply gravity, make use of Grav_Time (in seconds) to define the length of the gravity analysis. The desired Young's Modulus (E_Grav), and poisson's ratio (PR_Grav) to use during the gravity analysis should be provided as the last 3 parameters as shown below.
