Engine Keyword Time step defaults for all elements.

$Δ T_{s c a}$ $Δ T_{\min}$

Field	Contents	SI Unit Example
$Δ T_{s c a}$	Default scale factor on time step for all elements. Default = 0.9
$Δ T_{\min}$	Default minimum time step for all elements.

If the time step of a simulation reaches $Δ T_{\min}$ , then the following actions will happen depending on which element type is controlling the time step. For /BRICK or /QUAD elements, the simulation stops and a restart file is created. For /SHELL or /SH_3N elements, the element controlling the time step is deleted from the simulation. For all other element types, $Δ T_{\min}$ is not used.
