Dear Prof. Taylor,
I modified the geometry to be one quadrant of cylinder and I constructed surfaces with appropriate master/slave surfaces.
The issue with penetrating surfaces still exist. Can you please let me know how to define norm and penalty parameters correctly.
Modified contact code:
contact on
surface 1
nurb nf,1
nfac,,5
surface 2
nurb nf,2
nfac,,2
norm minus
pair 1
nur3 1 2
solm penalty 1e6,,0
augm
quadrature,,2,2
end contact
inter
batch
prop,,1
dt,,0.60
loop,time,20
time
loop,,10
augm
loop Newton 100
tang,,1
next Newton
next
dt,,0.01
npvi,ts,2,3
next Time
end
I am also forwarding the input file for your reference. It would really help me if you can point out the error in my input file.
Warm Regards,
Chandra
