  • Element failure or numerical error in user material in Abaqus explicit

    Dear all,

    Iím working on a simulation of an impact test according to ASTM D 3763. For this test I calibrated a material model (Three Network model) and want to do the simulation axisymmetric. I have checked multiple times all input parameters but every time I submit the simulation this error occurs. And I think there is something wrong with the user material.

    If I perform the simulation in 3D it works just fine but takes a long time to solve. Has anyone experience with the use of the TN- model in a axisymmetric explicit simulation ? Any tips or advice would be very helpful
    Full error: Element failure or a numerical error occured in the user material model.

    Best regards,

    Koen
