    Abaqus 6.12 is running very slow suddenly

    Try to manually download from website and upgrade your graphic card's drivers. It helped me.

    Volumetric locking in CPE3T elements - possible?

    Is it possible, that volumetric locking will occur during compression of CPE3T elements, if the material is elastic (without plastic behaviour)? The Poisson ratio of the material is 0.3.

    Time Increment in DFLUX subroutine

    How can I get the time increment in DFLUX subroutine? There is no variable DTIME there. I thought about using some kind of substraction equation where I substract a variable containing total time at the end of the previous increment from the actual total time TIME(2). Do you have any idea how...

    Different mesh density on the individual part

    Mustaine, I did what you said. I enforced local mesh seed to two cells. Aprproximate element size was 5 and 1 respectively. I marked option: "Do not allow the number of elements to change". After that, when I tried to mesh the part, the message showed up: Did I something wrong...

    Different mesh density on the individual part

    I see. How can I do it with the partition? It is good that Tie will be added automatically, because it will save a lot of time. And saving time is the purpose why I started this topic.

    Different mesh density on the individual part

    Hello, Look at the figure: Here are two parts TIE'ed together and the mesh densities on them are different. Is it possible to obtain the same results using one part with partitions? I tried to do that, but I can only change the number of elements on the thickness of partitions.

    Separation of two bodies

    Thank you, I will check the manual.

    Separation of two bodies

    Hello Lets say, that I have the situation as in figure below: There are two elastic parts. They are subjected to compression and tension as the arrows indicate. There is some friction between the parts and the substrate. Now, normally parts will separate from each other at some point. I want...

    Matching the meshes of two parts

    Mustaine, your trick is nice to match meshes, however contact between cylinders doesn't work when I do it. I have problem with my analysis, so I thought that matching these meshes could help. But maybe I should try something else. I will describe my problem. The scheme of the model is given...

    Matching the meshes of two parts

    I do not know how to much two meshes of different parts together. I want to have nodes from surfaces of these parts in the same positions (at edge at which these surfaces are in contact). Below is the screenshot from Abaqus: I tried changing node global sizes and local seeds, using different...

    Abacus runs really slow

    Upgrade your graphic card drivers.

    Ball bounce from the material

    Great clues Mustaine3, thank you. Mass scaling was activated. It was a problem. Now it is ok.

    Ball bounce from the material

    How can I model ball bounce of the rigid body from elastic-plastic material? I am using Abaqus/Explicit. There is a ball, which initial speed (predefined field) is 20 m/s. A ball is moving towards the fixed on the upper side steel plate as can be seen below: But after the contact was...

    XY Data - Abaqus gives me many stress values for identical time step

    MMmm, so I should ask for "element nodal"? And then choose the node which I want from generated nodes of this element? Or maybe there is a better method?

    Hi Dave, This box was checked already.

    XY Data - Abaqus gives me many stress values for identical time step

    In visualisation mode I click "Create XY Data", then I choose "ODB field output", then "Unique nodal" (in position). I choose "Mises" from "S: Stress components" ("S.Mises").

    XY Data - Abaqus gives me many stress values for identical time step

    When I extract the stress values from the results by XY Data option, it gives me something like this: Step time Stress 0 0 0.01 0 0.02 0 0.035 0 0.057499997 0 0.091249995 0 0.141874999 0 0.200000003 0 0.200000107 0 0.200000212 0 0.200000197 0 0.210000202...

    MPC - indestructible link - Video

    Thanks Bartosz, Your guidelines are very helpful. I am experimenting with very low connector stiffness now - results are nice. I tried also with *CONNECTOR FAILURE, but I do not understand clearly how limits for the forces/moments of the available components work. Also I have one question...
