Assembling two soil parts
Assembling two soil parts
(OP)
Hi all, I need a help for my consolidation problem. I don't know how to assembly two different parts of soil, because my job finishes with an error of overconstrains, using penalty friction.
Could you suggest any possible solution?

Could you suggest the better way to work in consolidation problem of different soil layers?
RE: Assembling two soil parts
until now no problems in the consolidation model should arrise unless there is something else wrong in the model. i noticed one of your threads where you are having a zero pivot problem arising which as i told you it could be a problem of the element you are using or the units..try this method and tell me if something wrong happens

You suggested me to deactivate the embankment set initially. How can I do it?
RE: Assembling two soil parts
you can leave gravity activated all times...you'd need to deactivate the whole embankment during the first step(check model change command in abaqus) and start activating its sets step by step (assume for example that the embankment hieght is 6 m..and you are building it 2 m by 2 m..so you should divide the embankment to 3 sets 2 m each..and activate them one by one in each step)
lets assume the whole embankment set is called emb..and then you divided it into 3 sets (2m each)emb1,emb2,emb3
so during the first step in you analysis
step1
*model change, type=element, remove
emb
step2
*model change, type=element, add
emb1
step3
*model change, type=element, add
emb2
step4
*model change, type=element, add
emb3
Just make sure there is perfect contact between different sets
