Hello,How did the elmer find the boundary conditions?
Posted: 15 Dec 2021, 07:52
Dear friends，I use the two different conditions,i delete a lateral condition,but the result is so different,Result as the picture,the first's surface is the second's bed.i don't know why? Do you know? Thank you,brother!
Code: Select all
Boundary Condition 1
ComputeNormal = Logical False
Name = "sides1"
Target Boundaries(1) = 1
Flowdepth Skip = Logical True
End
Boundary Condition 2
ComputeNormal = Logical False
Name = "sides2"
Target Boundaries(1) = 2
End
!! DON'T CHANGE ORDER OF NEXT 2 BC's!
!! They are automaticaly created in internal extrusion
!! bedrock:
Boundary Condition 3
ComputeNormal = Logical True
Name = "bedrock"
Flow Force BC = Logical True
Bottom Surface = Equals "bedrockDEM"
Bedrock = Logical True
!Height = 0.0
End
Boundary Condition 4
ComputeNormal = Logical False
Name = "surface"
Top Surface = Equals "surfaceDEM"
! Referred by: Exported Variable 2 Mask = ...
Surface = Logical True
Depth = Real 0.0
EndCode: Select all
Boundary Condition 1
ComputeNormal = Logical False
Name = "side"
Target Boundaries(1) = 1
Flowdepth Skip = Logical True
End
Boundary Condition 2
ComputeNormal = Logical True
Name = "bedrock"
Flow Force BC = Logical True
Bottom Surface = Equals "bedrockDEM"
Bedrock = Logical True
!Height = 0.0
End
