Sehr geehrter Herr Doktor Dr.-Ing. Ronald Wagner! Sie leisten eine großartige Arbeit, indem Sie Ihr Wissen weitergeben und Videos hochladen. Natürlich werden Sie nicht viele Treffer auf Deutsch oder Englisch erhalten. Aber Sie leisten eine sehr große Arbeit. Ich danke Ihnen dafür.

[@hnrwagner]

Herzlichen Dank!

[@jhdsm7903]

Dr.Ronald. It's a great tutorial. Hope for More.

[@hnrwagner]

what do you want to see for example?

[@mohdtauheed5242]

Thank you very much for sharing this useful informative videos.

Dear Dr. Ronald>>Please tell me what are the tricks to consider the bond slippage between bars as truss elements and concrete???>>>> because by the connector is hard and not practical in most cases.

[@hnrwagner]

Cant say, never used it

[@amrmasoud5580]

Thanks Dr, I ask you have you a video for how to create UMAT for concrete ?

[@hnrwagner]

Why? there are concrete models in ABAQUS and also no, do not have any umat for concrete

[@saramogahed8702]

please, can you share the script which including steel cage and stirrups

[@wolferi9615]

The best

Thanks

[@amrmasoud5580]

Dear Dr. I have a questions, what is the trick to change the characteristics of CDP by adding new features because the existing CDP is not enough for all loading cases?

[@hnrwagner]

not really sure what you mean unfortunatly

[@Valera197615]

Do you have some of your teaching material dubbed in German?

[@hnrwagner]

Currently not, the views in English are already quite low, i think in German it would be even lower, i can try some lectures in German though

[@AmrAbdallah-kz7bz]

Thank you very much! Is there a video on reinforced concrete (embedded region constraint, creating multiple parts and materials, etc)?

Hi, why my abaqus popup this error "ImportError: No module named matplotlib.pyplot"? Btw, I have install the matplotlib in the python

Can you increase the video resolution?

its 1080p lol :D You want him to make 4k ?

[@hnrwagner]

the HD version of each videos takes a while after upload, depends also on video length, i think a few hours after upload, the HD version should be available

I can't hear sir.

[@Valera197615]

Thank you so much! You have very good and informative videos. You are doing a very great job. But the sound is very quiet. And there are no subtitles in English.

[@hnrwagner]

I will check how to add subtitles in English

Thanks Dr.>> I ask you in general what is the best regarding nonlinear analysis of RC, Abaqus or Ansys workbench? I think that CDP model in Abaqus is not accurate for some issues as cyclic loading and dynamic analysis>>> Solid 65 in Ansys is accurate than CDP>>> are you agree with me?

[@hnrwagner]

cant say as i have never worked with ansys

[@amrmasoud5580]

@@hnrwagner Ok, For scientific honesty>>> I have built my opinion based on the PhD dissertation that has compared between both regarding cyclic loading ,

[@amrmasoud5580]

Thanks Dr.>>> I ask you can the user create a new concrete model rather than CDP copied from other softwre as ansys into abaqus? if yes, please tell me how? to can benefit from the accurate concrete model form ansys into abaqus

[@hnrwagner]

I am sure that you can use a UMAT for this problem, however, this will be a lot of work.

[@nikastopar6365]

Thank you very much for this upload. I tried running the first part of the script, creating the model. The problem is that Abaqus creates the model, but not the part. Any suggestion as to why that happens?

[@hnrwagner]

have you tried using the complete script from here: github.com/hnrwagner/ABAQUS_Python_4PB_Concrete/blob/main/4PB_Concrete_Beam_001.py ??

[@nikastopar6365]

@@hnrwagner i did, but it didn't work. Could the problem be in the software version? I am using 2023.

[@hnrwagner]

Can tell you later this Day, i will try it with 2023 Version,should not matter though

[@hnrwagner]

tried it , works for me as intended, also was 2023 Version

please Dr. would you mind sending me CDP excel file ?

for this video, there is no CDP model in use ?

Hi Dr. ronald, I need help please, I try to create a script to perform an assembly constraint using coincident point, but the script does not recognize the edge and shows this error and it is strange because it already uses these coordinates in a tie constraint Warning: findAt could not find a geometric entity at (1050.0, 0.0, 0.0) AttributeError: 'NoneType' object has no attribute 'index' this is my code def constraint_point(x1, y1, z1, x2, y2, z2, instance1, instance2, model): vertice=() edg=() a = mdb.models[model].rootAssembly e1 = a.instances[instance1].edges myedge=e1.findAt((x2,y2,z2),) edg=edg+(e1[myedge.index:myedge.index+1],) v1 = a.instances[instance2].vertices verts1 = v1.findAt((x1,y1,z1),) vertice=vertice+(v1[verts1.index:verts1.index+1],) a.CoincidentPoint(fixedPoint=vertice, movablePoint=a.instances[instance1].InterestingPoint(edge=edg, rule=CENTER))

I do not know why you get those error messages, but I have linked the Python Script here: Python Script: github.com/hnrwagner/ABAQUS_Python_4PB_Concrete/blob/main/4PB_Concrete_Beam_001.py and it doest lead to those errors, I just tested it.
