How to become a vendor on CAE assistant
Great 👍
Hello I want to model a themo-hydro-mechanical analysis. As you know, Abaqus in the SOIL option just considers a fluid. But I want to calculate the pore pressure more detaild. How do you think I can add a more accurate analysis of the temperature-dependent pore pressure to the thermal-mechanical analysis? Is it necessary to write the entire process of hydro-thermal-mechanical analysis with UEL subroutine or can only pore pressure be added in each increment to thermal-mechanical analysis, i.e. use the sequentially coupled method via inpute file or UEL sobroutine? Best regards,
Great
Thank you for share this. Can l have the czm umat code?
Hi, thanks for your comment. the link in the description and to get access to the code, you should proceed through our website
Is there any option in abaqus to define a combined isotropic and kinematic softening with damage.
Hello Please tell me how to define shear failure of concrete in CDP model?
Hi, If you mean to define a parameter for that in the settings, there isn't such thing; the shear failure will be calculated by the Abaqus based on the compressive and tensile material properties you have provided.
The English should be improved overall. An example: at 7:34 "The strain is abstained....the curvature is abstained..." should be "The strain is obtained" because "to abstain" means means "to not to do something", "to refrain" etc
Hi, thanks for your comment and presicion. Your comments are noted and we try to make it better in our upcoming videos. You helped us alot.
Hi, i do all module accordingly but when solving why the results only show 0? Can i get help ?
Hello, the reason you get 0 results in stress or displacment because you didn't define boundary condition properly. and if you need a specific answer you must explain more. you contact us via our WhatsApp: +1 (740) 966-1814

Mam, how to view or import the model, results tab(left side).
Hi, thanks for your comment. I don't understand your question completely. can you be more specific? All I can say now to import a model in Abaqus, you have to use the "Import" option from the "File" menu.

At 16:00, it is stated that NTENS=12, but I couldn't understand it. Isn't the NTENS=6, and the total number of variables for strain is 12 which also makes dependent variables 12.
Hi, thanks for your comment. You're right. sorry for our mistake and thanks for noticing and informing us. The NTENS=6 and the number of state variables equal 12.

How to plot residual stress ?
Hello, First you need to obtain the residual stress of your model. One way to model residual stress is to use "Predefined Field" tool in Abaqus. next, it's better to create a path of nodes or edges of the region of your model where you need to analyze the residual stress. after that use the "Create XY Data" tool to plot.
You've represented it as a singular geometry, neglecting the joint with a pin connection, which is fundamentally incorrect for structural analyses. Truss joints are designed to permit rotation and resist translation exclusively. This idealization is inaccurate.
Thank you for your comment. In this video, we intended to show how to model a 3D truss with the truss elements. This idealization is not totally inaccurate; yes, there might be differences in the stress results at joints but it’s not like that the results are wrong.
Is there any way to get this older version of AM Modeler in Abaqus 2022? The newer version is too tricky for me, thank you!

Hello, thank you for your comment. The question you have asked is quite specific and would require some time to thoroughly review your file. Unfortunately, I can only provide answers to general questions here.

ruclips.net/video/D5MJ0D1OMF8/видео.html I followed all the stages, but to no avail, the program is full of errors
Hello friend, thanks for your comment. The reason for the errors might be because of the writing subroutine principles, which sometimes get tricky, and in the video, you shared its link, he may did not explain everything or make some simple mistakes, or you did. The writing subroutine and coding techniques must be learned. You can watch this video: ruclips.net/video/NI2WQZB8730/видео.html or you can see the full package that its link is shared in the description below.
Thanks so much for this video. Please I wish to understand want can make someone to define many steps.
You can define as many steps as you need for your simulation if it is logical in the simulation; you can do this using a python script which as so happens you can find an example of it in the videos of this package: caeassistant.com/product/python-scripting-in-abaqus-part1/ caeassistant.com/product/python-scripting-in-abaqus-part-2/
Thank you for these info I have a question What is the meaning of time period in step module of abaqus explicit
Hello, thank you for your compliment. The time period in Abaqus explicit means the physical time of your analysis. It determines how long your analysis want to simulate. For example impact simulation with step time equal 3 means that 3 seconds of the process will be simulated.
at 5:05 the point is not cleared properly
how to get more frames? or on what feature does the number of frames depend on?
In the Step module, go to the Field Output manager window, and select whatever Frequency option you want to set the frames. The max number of frames in an analysis can be number of increments, but due to saving storage memory, you can request fewer frames. You can see the article in the description (section 3 of the article) to understand this.
Great Video
Thank you for your comment.
Thank you for the video, but when I am using the truss elements i.e T3D2, I am getting the Warning "Solver problem. Numerical singularity when processing node TRUSS-1.8 D.O.F. 3 ratio = 4.21658E+15." How to avoid such a problem.. Can u suggest me... Thank You....
Hello, thanks for your comment. check these three things in your model: 1. Check your material properties. 2. Check the Displacement you applied in your model; it might be too high for your model. 3. Check the number of elements. In a truss, each member of it must be assigned to only one element. After you checked the items above, if the problem still exists, your model must be checked completely.
