    Transfer variable/data from Abaqus fortran-based subroutine to Python 3.8

    Hello everyone, I am working on a neural-network-based hyper-elastic model. I've finished training the model and now I want to implement it into Abaqus UHYPER subroutine. I have .py file to calculate U=U(I1,I2,J) as well as derivatives of U w.r.t I1, I2. May it be possible to transfer data from...

    Abaqus Subroutine to remove element after each increment

    Oh yes, thank you so much. I've got this after adding the keyword. You can see in picture focusing on blue mark, 2 brick elements now sharing one node so they will be highly distorted in next increment.

    Abaqus Subroutine to remove element after each increment

    I am quite new to that option. I see 2 sub-options (energy fraction, damping ratio) in Step Edit Dialog. Can you suggest me which option I should use?

    Abaqus Subroutine to remove element after each increment

    Even when a few elements have been deleted like this picture, the solver cannot continue. The plastic property of material is: *Plastic 100.012, 0. 110.061, 0.00032 120.788, 0.00058 130.379, 0.00091 140.082, 0.00133 150.12, 0.00188 160.26, 0.00262 170.217, 0.00356 180.139...

    Abaqus Subroutine to remove element after each increment

    Yes, the elements has been deleted. I am simulating a tensile test of a specimen with Abaqus Standard. But when it has broken into 2 pieces, the solver cannot continue the next increment.

    Abaqus Subroutine to remove element after each increment

    I am so thankful to your instant help. I alse found ordering of LE variables. Here is my code SUBROUTINE USDFLD(FIELD,STATEV,PNEWDT,DIRECT,T,CELENT, * TIME,DTIME,CMNAME,ORNAME,NFIELD,NSTATV,NOEL,NPT,LAYER, * KSPT,KSTEP,KINC,NDI,NSHR,COORD,JMAC,JMATYP,MATLAYO, * LACCFLA) C...

    Abaqus Subroutine to remove element after each increment

    I want to get maximum principal strain, from Abaqus Document, which LEP. When I used GETVRM to get that value, I am not sure whether ARRAY(1)is the value I want.

    Abaqus Subroutine to remove element after each increment

    I did a code with USDFLD and DEPVAR. I set state variable to control element deletion as 2. If criterion has reached, I set STATEV(2) as 0 to flag the material point to be deleted. But somehow the values of STATE(2) in my ODB file are not only "0" and "1".

    Abaqus Subroutine to remove element after each increment

    Thank you. I found the tutorial to delete element using state variables with Abaqus/Explicit only. I want to remove element in the same way it does with *Model change option in the input file without developing material model by UMAT.

    Abaqus Subroutine to remove element after each increment

    Hello everyone, I am writing a user subroutine in Abaqus to remove element that has reached damage criteria ( as a function of max principal stress and strain ). I knew how to use URDFIL to read data (stress/strain) in integration points of C3D element so I am wondering if there would be a...

    Copy front view from Drafting module to a sketch in Catia V5.

    Yes, i did copy the view . And if you isolate the view, the content in the view would turn into black. Is there any difference between your version and mine ?

    Copy front view from Drafting module to a sketch in Catia V5.

    It still doesn't work for me. Can you give me some step-by-step pictures ? http://files.engineering.com/getfile.aspx?folder=845dfde2-5aa8-460e-939b-ef18b065a7bc&file=Untitled.png

    Copy front view from Drafting module to a sketch in Catia V5.

    Would you guys show me the way to copy 2d generative drafting to a sketch in Part Design ? I've tried the way in this video but nothing happened after paste command .
