Hi All,

WARNING MINIMUM TIME STEP  -0.4725E+18 IN INTERFACE        784 (DTMIN=  0.0000E+00)

 

 

Is the time step goes in negative.!!!

 

 

I haven't specified any values for dtmin in my type7 interface (id .784).

But I am getting this warning at the start of my engine.

 

Any Hint PLs.

 

Regards,

SUBHU

    Hi Subhu,

    This seems to be bit strange!!!.

    For an interface, the time step is calculated from the stiffness and thickness of master and slave components. I doubt with the material parameters, especially check the unit consistency followed for the material parameters.

    If everything seems fine, then please share your model file in the secure dropbox link.
