actually i am comparing 2 model one is by using sub structures and other is without substructuring The use of sub structuring is to reduce the solving time.. but in my case the model with sub structures is take more time to solve than the model with out sub structures i guess because of this...

Hi My run is successful with substructure modeling. But I have some doubts. 1) There are warning messages in the .msg file showing Zero pivot and numerical singularities 2) With the warning messages, sill my job completed and i got the results. Why is it so

ok thanks for you help i will try it out with all your inputs..

if there are any contacts present in substruture, do i need to create the contacts again in the usage level i my case i have contact surfaces between sub structure 1 and sub structure 2

okay thanks for your support.. i would also like to know when do i need to create the actual loadcases like prtension and concentrated forces in the model.. Can i create the actual loads and boundary conditions after assembling all the sub structures

which means i have create manually the COUP Kin elements in abaqus CAE to connect the bolts ?

after importing how do i connect the COUPKIN elements of Sub strutures 1 & 2 to the bolt end points

okay i have generated substructures for both the blue parts and bolts are considered as standard parts... but once i import the .sim files the substructures are not connected to each other and the COUP KIN elemenst are missing in the model why is it happening

okay what about the bolts.. will it be part of substructure 1 or sub structure 2 and once i run the generate substructure step and import the Sub_Z1.sim part file the COUP KIN elemensts assosiated to retained nodes are not present in the model

Pleas refer the schematic of the assembly.. i have multiple bolts hence multiple retained nodes https://files.engineering.com/getfile.aspx?folder=67187af2-08ef-45ac-a635-a216b0f879a0&file=substructure.PNG

thanks for your answer! i have seleted the nodes of bolt ends as retained d.o.f nodes which are connected to COUPKIN elements between the CASE and Housing parts.. But after generating the substructure i imported the part in the new model but the sub structures are not connected at the...

Hi all, I am doing a contact, geometric non linear analysis of transmission parts (case , housing, cover etc...). Here i want to check the contact opening between case and housing parts. Housing and CASE are connected through bolts and COUPKIN... I want to use substructuring technique for...

Thankyou for your support i got the answer

Tools in which application Abaqus CAE or Hypermesh or Hyperview

thankyou for the reply.. But is CTANDIR output variable abailable in abaqus? Can we extract the total slip form CSLIP1 and CSLIP2

Hi all, i am working on a contact analysis and i would like to see the slippage between the two surfaces i have requested the CDISP output in the analysis and i am getting CSLIP1 and CSLIP2 as results. i want know the difference between CSLIP, CSLIP1, CSLIP2 and CSLIP is not available in the...
