This option is used to indicate that a dynamic coupled thermal-stress analysis is to be performed using explicit integration.

Include this parameter to specify explicit time integration.
Include this parameter to specify that this step should use a fixed time increment that is specified by the user.
Include this parameter to indicate that variable, automatic time incrementation using the element-by-element stable time increment estimates should be used. This method will generally require more increments and more computational time than the global time estimator.
Include this parameter to specify that this step should use a fixed time increment that will be determined by Abaqus/Explicit at the beginning of the step using the element-by-element time estimator.
Set IMPROVED DT METHOD=YES (default) to use the “improved” method to estimate the element stable time increment due to the mechanical response for three-dimensional continuum elements and elements with plane stress formulations (shell, membrane, and two-dimensional plane stress elements).
Set IMPROVED DT METHOD=NO to use the conservative method to estimate the element stable time increment due to the mechanical response for three-dimensional continuum elements and elements with plane stress formulations.
Set this parameter equal to the factor that is used to scale the time increment computed by Abaqus/Explicit. The default scaling factor is 1.0. This parameter can be used to scale the default global time estimate, and it can be used in conjunction with the ELEMENT BY ELEMENT and FIXED TIME INCREMENTATION parameters. It cannot be used in conjunction with the DIRECT USER CONTROL parameter.
