    Hi Pravin Kumar,

     

    the issue could be with the modelling method. Please check the following:

     

    • furnish mass, inertia values and be correct if you are performing dynamic simulation
    • if you are using contacts in your model check contact properties. it is recommended to manually mesh the geometry with a fine mesh where the bodies come in contact
    • play with solver parameters like h_max, DAE, etc.. also try changing the integrator type to VSTIFF if there are flex bodies.

    please let us know if any of the above helped you.
