Δ T min Default minimum time step for all elements.  


  1. 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.
