    Question about passing information from VUSDFLD to VFric_COEF/Vfirc

    Hi guys, i am working on a problem using VUSDFLD and VFRIC/VFRIC_COEF. I am able to get the stresses using VGetVRM and store it as field variable in VUSDFLD. And I want to use this stored field variable to update friction coefficient in VFRIc, my question is how can I use my stored field...

    Material calibration

    Hi guys. Does anyone have good advice or methods for material calibration. Like I have an unknown material, I had a compression test and the output is a force displacement curve, and I need to came up a an stress-strain for this unknown material. Does anyone have good experience for this task...

    Possible to add initial strain in ABAQUS?

    Hello all I am wondering if I am able to add initial strain in ABAQUS? I know I can use initial stress from predefined field. How about initial strain? Can I do that in ABAQUS? any work around? Thanks Lee

    Mass scaling not working?

    Hey guys, I have a quick question about mass scaling. In my current model I have applied semi-automatic mass scaling to a target time increment to 8e-7. However, looks like it's not working at all at where the time increment start to decrease. As you can see the attached image, the percentage...

    How to apply a B.Cs that move the object in 45 degree? or certain angle?

    Hello all, I am a basic question for applying a displacement B.C. in ABAQUS. Do you guys have any idea about how to apply a displacement B.Cs on a reference node that allow the object to move in 45 degree or certain angle? for example, when I do peeling test, can I can pull the peel edge in a...

    Adhesive vs cohesive

    Hello ABAQUS users, I am trying to modeling the adhesive vs cohesive in a a peel test. I am wondering is anyway that I can use cohesive contact of top of cohesive element? I am trying to understand the adhesive failure at the the interface vs cohesive failure in the cohesive layer. please help...

    switch rigid body on and off between steps

    Hello everyone, I am wondering is there any possibility that I can switch rigid body on and off between steps? or can I use import analysis to import the rigid body as deformable? Best Lee

    getSubset not working on COORD?

    Hello everyone, I am working on a script to use getSubset method to access the stress and coordinates from a certain element set. I just noticed a problem with COORD and I I'm doing exactly the same for both, but it only works for the stress. For COORD I always get an empty array. I've posted...

    nblock and coordNp in vdisp

    Hello everyone, I am writing user subroutine using vdisp. My I ask why the return value of nblock is always 1 and the coordNP is always 0? the coordNp should return current nodal coordinates at 1,2 & 3 direction right? Please help if My understanding is not correct. Part of my code is below...

    Control motion use VDISP

    Hi everyone, I am trying to define the movement of a conveyor belt, the conveyor moving with constant velocity, may I get your advise what is the best way to define the BCs for this type of simulation. Since the belts driven by driving rollers are not able to move stably, I am thinking use...

    USE UEL and USDFLD together

    Hello everyone, I am currently working on a solid phase tranfermation problem in ABAQUS. I am using UEL to define myself element, USDFLD to do the phase transfermation. I am wondering if I can ahare variables between this two subroutines? can I use them togather to complish my simulation? any...
