Simlation error

please provide some information about this error, 'The nonlinear system solver in the time integration could not converge'

English

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.
