    How to select both the exterior and interior surfaces (All Entities) of an element when creating surfaces in Hypermesh?

    Hi all, when I create a surface in Hypermesh, why can I only create an exterior surface similar to a skin, and how can I select the interior surface of element? It is similar to the ‘All Entities’ option when creating surfaces in Abaqus. As shown in the picture below. How can this selection...

    Failure of symmetric boundary constraints in Abaqus

    Hi all, I have defined node symmetry boundary constraints in Abaqus/Standard 3D (e.g. the plane of symmetry is the XY plane and I constrain the Z-direction movement of the set of nodes that lie on the plane of symmetry), but they still produce a movement in the Z-direction! Can anyone help with...

    Why don't chips curl when the cutting process is simulated using the CEL method?

    Hello everyone, I am doing a simulation of orthogonal metal cutting process using CEL method. To make sure the simulation is better, I found a very good SCI paper for reference, but unfortunately I didn't reproduce the perfect chip simulation in the author's paper, the picture below shows the...

    ALE method for 2D metal cutting simulation in Abaqus/Explicit?

    Hi everyone, I've recently been using Abaqus/Explicit to do a finite element simulation of 2D metal cutting using the ALE method, and I've seen a blogger on YouTube do a similar simulation(https://www.youtube.com/watch?v=6wVFSw94Rkk). Still, his results are much more normal than mine. Doesn't...

    Johnson-Cook damage model ?

    Hi, everyone. I want to ask a question about the JC damage model that has been bothering me for a while now, and I feel that it might turn my previous knowledge upside down. Is the strain value calculated by the Johnson-Cook damage model used in Abaqus software the fracture strain? Or is it the...

    Serious error report of mesh distortion!

    Hello, everyone. I carried out the finite element simulation of the metal cutting process in Abaqus/Explicit, but there was a serious error report in the mesh distortion, and the simulation was aborted. Later, I reduced the mesh size by half, and the failure displacement was also reduced, but...

    Abaqus2022 cannot call logical processor

    Hi all, My computer has 2 cores(4 logical processors), and I set the number of multiple processors in Abaqus is 4. I submitted the job in Abaqus2021, and it ran well, but it was aborted and prompted the errors as I submitted the job in Abaqus2022. The error was "The number of cups (4) exceeds...

    Kinematic contact & Penalty contact

    Hi all, I'm running a metal cutting simulation with Abaqus/explicit. Generally, I use the Kinematic contact between the tool surface and workpiece surface(node-set), but when I set the rigid tool to rotate, it suggests that I can't use kinematic contact anymore, I have to use penalty contact. I...

    5% rule between Kinetic energy and internal energy

    Hi all, I was running an explicit simulation on Abaqus. I wonder if I don't use the mass scaling to speed up my simulation, but the kinetic energy is far more than 5% of internal energy, does the result match the real phenomenon? Thanks.

    Mass scaling in metal cutting simulation

    Hi all, In the simulation, mass scaling can be used in quasi-static processes, but can we use mass scaling in dynamic processes such as metal cutting? Mass scaling significantly impacts the simulation in high-speed rotary cutting, and the output kinetic energy is always much larger than the...

    The cpu time doesn't show in Abaqus simulation

    Hello, everyone. When I run the simulation on Abaqus, the CPU time is not displayed in the monitor panel. Can you answer my confusion?

    Boundary conditions setting error

    I tried to use Abaqus for external turning simulation, set the workpiece speed to 6.28/s, and set the analysis step time to 1. Theoretically, the workpiece should rotate one revolution, but the output shows that the workpiece reference point did rotate one revolution, but the rotation involved...

    Abaqus:multiple processor error

    My computer has four processors, and I set up multiprocessors to run in Abaqus, but the Status file shows that all tasks are assigned to #CPU1, the task manager shows that the CPU occupancy rate is less than 20%, and the simulation speed is very slow. My dear friend, could you help me solve my...

    TWS AdvantEdge doesn't show the completed interface

    Can someone take a look at this for me? My TWSAdvantEdgean doesn’t show up all the way to the open interface[neutral], like the one below. appreciate you for your kindness!

    How to display the chip in cutting FEM

    Hi all, I am a new ABAQUS user and modeled a cutting process using dynamic explicit. The results make sense but it doesn't show the separated material and doesn't show the chip at all,I want to see the chip formation and I have already selected the STATUS but it doesn't work. can anyone help me...
