Problem with choosing Master -Slave surface
I'm new in ABAQUS and trying to model a cone penetrating soil surface a axisymmetric surface but when i run the program it showing the error
rror in job Job-1: THE SLAVE SURFACE ASSEMBLY__PICKEDSURF21 HAS 17 NODES IN COMMON WITH ITS MASTER SURFACE ASSEMBLY__PICKEDSURF20.
Error in job Job-1: THE SLAVE SURFACE ASSEMBLY__PICKEDSURF23 HAS 2 NODES IN COMMON WITH ITS MASTER SURFACE ASSEMBLY__PICKEDSURF22.
Error in job Job-1: Permeability is specified on 45030 elements but the initial void ratio is not defined. Use *initial conditions to the value. The elements are identified in element set ErrElemPermNoInitVoidRatio.
Error in job Job-1: CONTACT PAIR (ASSEMBLY__PICKEDSURF23, ASSEMBLY__PICKEDSURF22) HAS NOT BEEN DEFINED AND HENCE, CANNOT BE USED FOR *MODEL CHANGE
Anyone know about this problem. any suggestion on this are most welcome
Void ratio error
You can view the set in the Viewer by displaying the group ErrElemPermNoInitVoidRatio if it can help. I am afraid you need to define define some initial void ratio using the key word
*initial condition,type=ratio
Your node set name, void ratio value
If the interaction error persists, you can try to define the two surface giving meaningful names before to the master/slave assign in the surface to surface contact menu, not just by picking. lso, try to swap master / slave and change the mesh density in the contact zone to see if it makes some difference. Make sure you adjust the contact surfaces so that overclosure doesn't occur and chech that normals are defined opposite.
