I performed sequentially coupled thermal-stress analysis in Abaqus CAE/standard using static general step(Direct method & Full newton solution technique) for 5000 second. Analysis completed with no error but some warning(excessive distortion & large strain increment on very few point) given by abaqus during few unattempted(1U or 130U like that) increment. To make the soluton converge, abaqus automatically cutback the timestep and then it works & solution completed with no error.

My question is that should i worry about warnings or will these warnings gonna affect my subsequent increment or whole solution? (since these warnings given only during unattempted increment, after cutback timestep, no warnings given further)
