    Help needed to simulate trolley travel on a cable

    Hi, I would like to simulate a trolley traveling over a tensioned cable in Abaqus. I have already solved (kind of) this problem in LS-Dyna using seat belt element for the cable, rigid body for the trolley and a slip-ring between the two. However, I would like to validate the results from...

    Mesh size and material dependency

    Dear Friends, I have two similar structures. The first is modeled with viscoelastic material and subjected to quasi-static analysis,lets call this 'model A'. The other is modeled with isotropic elastic material and subjected to static analysis, 'model B'. The two abaqus models are exactly the...

    Zero reaction force

    'Element size' was the culprit :( A finer mesh solved the problem. Thanks, Niranjan

    Zero reaction force

    Thanks corus. I am performing a load based static analysis. Actually, I am using this model for optimization purposes. I am varying certain dimensions and material properties every iteration. I see that the analysis is completed with sensible results in some cases, while in some other cases...

    Zero reaction force

    Thank you Oriol and Corus. But unfortunately, my problem is not yet solved. @ Corus: I dont see even a single node in contact with the surface (CPRESS values are zeros). My question now is, how can Abaqus solve a job "successfully" when equilibrium equations are not satisfied? -Niranjan

    Zero reaction force

    Hi, I am working on a wheel like structure in contact with a surface. Its a load based model in which a predefined load is applied at the centre of the wheel. Once the wheel is fully loaded, I am supposed to witness the reaction force on the surface to be equal to the applied load. But in my...

    Problem with Beam elements

    Hello everyone, I get the following warning message during the analysis, can anyone help me rectify in this? "For 1489 beam elements either the average curvature about the local 1-direction differs by more than 0.1 degrees per unit length as compared to the default curvature or the approximate...

    Extract ALLCD history ouput using python script

    Found the solution pals :) required line in script: odb.steps['Roll_Static'].historyRegions['Assembly ASSEMBLY'].historyOutputs['ALLCD'].data Thought it might be helpful to others. Thanks anyways, Niranjan

    Extract ALLCD history ouput using python script

    Friends, Can anyone help me with the extraction of ALLCD history output for the entire assembly at the end of time step ('Roll_Static' in my case) using python. odb.steps['Roll_Static'].historyRegions['Assembly ASSEMBLY'].historyOutputs['ALLCD'] This is what I have so far and I am not sure of...
