    About the Hex Mesh

    You should to switch the SPC to ASET card The rigids element needs to be switched to rbe2 CONROD_Altair_Dis_ABAQUS.fem
  3. The mats1 card is used in the nonlinear subcase. But the loadstep of your model is “linear static” ,you should change it to "nlstat".

    stress concentration problem of contact

    Hi @Prakash Pagadala I have already sent the model to you, thanks !
  6. Model description: A set of gears Load:Torque Non-linear analysis conditions (NLSTAT) There have contact between the gears (Slide) Problem Description: The ideal result should be that the largest stress is at the root of the tooth, but the analysis result is that the largest stress is at one point of the tooth surface. This maybe stress concentration. Is it a model problem? Or, if not, how to solve the stress concentration problem caused by this analysis. When I look at the results at different times, stress is still relatively uniform even at t=0.9, but stress concentration occurs at t=1.0. Is the load equally divided? The following pictures show the stress results On the left is t=0.9. On the right is t=1.0.

    *** INTERNAL PROGRAMMING ERROR # 8016 ***

    @ Prakash Pagadala Hi, Thank you for your reply. But,I am sorry that the model is confidential.

    *** INTERNAL PROGRAMMING ERROR # 8016 ***

    @ Prakash Pagadala Hi, It really worked, I got the results of the analysis. But, what causes this? softwear bug? thank you very much !

    hi @ Prakash Pagadala It does'nt work . The erro still exists.

    @ Prakash Pagadala OK, I'll delete“ rforce” to try it. Thanks !

    @Prakash Pagadala Thank you for your reply I have update to the 2017.2.2 here is the entire .out file Zhou_m_LG3.out and I have deleted the card “nlout” and “NLmon”
  13. Hi, I'm getting following error from Optistruct. I used the Hyperworks 2017.2 The .out file print "Nonlinear solution has converged" ,but with this erro and no last h3d results. how can I resolve this issue? Thanks,

    Analys of cover detaching with optistruct

    你的模型有以下几个问题: 1、最大的问题:模型中 网格有好几个地方是没有连接起来的。 检查自由边可以检查到该问题。 2、你定义的接触有问题,接触法向 与单元的法向 没有匹配起来。 建议将 壳单元 直接定义成接触体 3、你最好先把接触问题 调整好了之后,你在设置其他的非线性问题。 -------------- Your model has following problems: 1, the largest problem: Free edges.Mesh of several places were not connected in the model. Check the "free edges" to check this problem. 2, the contact problem: the normal of the contactsur did not match the element,and the normal in the interface(group) were reversed. It is recommended to define the "elem entity" directly. 3, you'd better solve the contact problem firstly,and then, set other non-linear problems.
