Hello, How are you.? How do you approach for edge to edge contact in abaqus standard

[@FemexIran]

Hi. Thank you. You can define General Contact to account for the edge to edge contact in Abaqus/Standard or Abaqus/Explicit.

Hello l have a problem in abaqus when l simulate . "Machine precision requires a time step greater than 2.22000e-16"

hi. what is your simulation about ? have you set the time period less than that value ? please explain about your modeling in more details.

how can i resolve VALUE FOR PARAMETER NSET CANNOT BE MORE THAN 80 CHARACTERS

[@FemexIran]

Hi. this error means that the name of a surface or set or every thing else in your model exceeds 80 characters and it is too large. in the Abaqus, the name of everything must be less than 80 characters.

[@saadulhaq6572]

@@FemexIran what should i do now?

[@FemexIran]

@@saadulhaq6572 you must check all of the names in your model and find the names with more than 80 characters and rename them in order to have less than 80 characters.

Hi, i have a problem. My analysis is coupled temp-displacement, how can I solve the "too many attempt error"?

[@FemexIran]

hi. as I mentioned in the tutorial, this error can have a lot of reasons. so to find out the cause of error, your model must be checked. to resolve the error, you can use our online tutoring service. for more information, please send an email to me: [e-mail]

Thank you sir for the wonderful video 👍

[@ziedmili4478]

thank you for the details. I just start to build the model for a steel bridge in Abaqus. The bottom and top flange have variable thicknesses while the web thickness is constant all along the girder. I tried to create the parts with solid and shell shapes but still, the job can not run properly. Is there anyone who succeeded to build a steel girder bridge model? What do you recommend: create different parts (top and bottom flanges and web) separately and then connect them or create I shaped parts and attribute thickness to each part connect them using tie constraint?

[@мишамихайлов-х2р]

Hmmmm, I would say - check dat and msg files first! Don't start to play with setting, until you check and fix warnings. There are keys there

[@FemexIran]

Hi. Most of the Abaqus warnings do not affect the solution and they are only for caution. Having or not having warnings do not guarantee your solution at all. There are much more powerful tools and indicators for finding the convergence issues like job diagnostics tool. Actually resolving convergence issues in a nonlinear FEA can be much more complex that you can imagine. We have two other free tutorials about how to interpret the warnings. here are the links to them: kzbin.info/www/bejne/Z4WrhnyYqJKXgNk kzbin.info/www/bejne/g5zYdWSGgplordk

[@мишамихайлов-х2р]

@FemexIran 1. Max number of increments exceeded. 2. Force/moment equilibrium is not achieved 3. Excessive distortion of elements 4. Excessive rotation in dof at the point And so on. From my point of view this is really not too bad idea to look in output files to check what is going on in simulation. I used to work w/o graphical interface, so both mentioned above files are key for problem solving and debugging.

[@FemexIran]

@@мишамихайлов-х2р I have seen a lot of cases that the analysis was completed even with the mentioned warnings. Because of this I say that resolving them does not guarantee the completion or not completion of the analysis. This is because of the complexity of nonlinear FEA and I do not use the warnings as my main tool to resolve the error.

Thank you so much sir for the video. The next, I am facing error; 157 element have no property definitions. How can I fix this error sir?

[@FemexIran]

hi. this error has two probable sources. the first one is that maybe you have not assigned section to some parts. the second one is that maybe you have not assigned appropriate element type to some parts that is not consistent with the assigned section in property module.

[@FemexIran]

hi sir. if your model has convergence problem you will encounter with one of the errors: " too many attempt" or "time increment required ..." . in mechanical problems, the last way for solving these errors is uisng dynamic implicit step or dynamic explicit step if possible. you can contact me and explain your model in telegram or whats app or by sending email. then we give you solutions.

[@simonliu2415]

it does not work at all. i do as you told, i use the implicit dynamic ,quasi-static, it does not work at all.too many attempts means you model is not correct.

[@FemexIran]

hi. in some simulations the only choice is the use of dynamic explicit step because the model is highly nonlinear and we must change the solver.

While this video didn't solve my issue (still trying to understand why, perhaps something to do with my student version) but the video is incredible nonetheless and I hope that it at least helped others. Thank you

[@FemexIran]

hi. this video includes some general guides. as this error can be occurred nearly in every simulation that Abaqus/standard solver is used, the way of resolving the error is very case dependent. many reasons can be the cause of occurring this error. you can contact us in order to give you consultancy for resolving your simulation errors. this is one of our main services.
