Hello everyone,
I am new to Thermal Analysis at UDEC. I want to achieve thermal-induced stresses due to changes in temperature of a voronoi model.
This is the following code I used:
block config thermal
block tolerance corner-round-length 1E-2
block tolerance minimum-edge-length 2E-2
block create polygon 0,0 0,10 10,10 10,0
block cut vor edge-maximum 1.0 round 0.01
block joint-delete
block zone gen edge 1.0
group zone ‘User:ID109’
block zone cmodel assign elastic density 500 bulk = 1E6 shear = 2E6 cond 20 specheat 0.2 range group ‘User:ID109’
block contact group ‘Rock:Sandstone’
block contact cmodel assign area stiffness-shear 1E9 stiffness-normal 1E10 friction 30 cohesion 1E5 dilation 5 range group ‘Rock:Sandstone’
; new contact default
set jcondf joint model area stiffness-shear=1E9 stiffness-normal=1E10 friction=30 cohesion=1E5 dilation=5
block gridpoint init temperature 30.0
block gridpoint thermal-apply temperature 100.0 range pos-x 9.9398,10.1562 pos-y -0.2963,10.1562
block thermal cycle
block thermal cycle age 5.0
This is the error I get:
failure in coef2
Can somebody please convey the correct procedure to perform this thermal analysis?
Thanking You
