I'm trying to use coupling option in hydromechanical analysis of an underround excavation. While processing to excavate the tunnel, the software shows an error saying:
*** Blocks may not be joined after zoning if CONFIG GW is used!
I will appreciate if anyone confronted with the same problem could help me.
Regards.
On a related subject re coupling, as modelled in UDEC-BB, I do not know if 3DEC uses the Barton-Bandis concept of physical apertures E > or = to hydraulic apertures e, therefore switching between mechanical M and hydraulic H calculations. Also watch out for the often unrealistic too close values of normal and shear stiffness. The former kn is entirely different to ks - it should be 10 to 50 times greater. Remarkably one sometimes see them put equal.
Great points Dr. Barton,
I tried to assign values of the mentioned parameters in the same range you've said and the HM switch also was already done. Please let me know if there's another remarks.
Thanks alot.
Masoud Mazraehli , Hello, now I have encountered the same problem. How did you solve this problem? What is the cause of this error? I would be very grateful if you could answer that.
