Write out results for each substep?

Is there a way to write out results for each time step when using the implicit solver for NLSTAT in Optistruct?

Or, should I convert the model to BLOCK and run it with the RADIOSS explicit solver?

    Hi,

     

    Please use NLOUT to output incremental results.

     

    Please refer to OptiSrtuct help for more information.

    Thanks for the tip.

    Including this link would have been most useful but I managed without it.  link to invoking NLOUT in BULK and SUBCASE unsupported cards

    It appears that the writing of the results is suppressed until the solution has converged, which is where my interest lies.

    I know running in RADIOSS writes out results for every converged substep.

    Can one just create an NLPARMX with some timestep limits and NPRINT -1 to write out substep results?  This way the export

    is created behind the scenes for the starter and engine files, correct?

    With a model that takes 19-21 hours to run, it is reassuring to check in periodically and make sure model behavior is proper early in the solve...
