I am trying to use EREINF command to embed my reinforcement in my solid concrete elements. I am currently not modeling any non-linearity.
When viewing results from a simple analysis there are erroneous graphs that make me doubt that the EREINF command is working properly. The reinforcements that are aligned in Z direction are showing bulging with large deformations which is very strange. I have 8 sets of reinforcement defined. 3 of them are in Z direction, all have similar erroneous results. The rest of them look fine.
All my solid elements are quad and I did not change any of them. The loading is displacement control in Y direction upwards.
I would be grateful if someone could take a look at my code and help me. I use version 2019 R1 Academic.
Attached are deformations from two sets of reinforcement (deckl and deckt) in my model.
This is the APDL code I used:
*SET,MAT_ID,2002 !STEEL REBAR MATERIAL
AREA_3=71 ! #3
AREA_4=129 ! #4
AREA_5=200 ! #5
CMSEL,S,NS_DECKL,ELEM !! DECKL
CMSEL,S,NS_DECKT,ELEM !! DECKT
!!Here is the rest of the definition of reinforcement similar to the two above I removed for this post.
