Incrementation Question

Hello!

I am attempting a dynamic, temp-disc, explicit simulation in ABAQUS, and even though I have my max time increment set to 1E-06, the steps seem to be at an increment of 0.001 when I submit the job. Does anyone have an ideal of why this may be, or how I can return it to my intended time increment? Having that specific time increment is important for my simulation.

Thanks in advance

I have attempted setting it as a both a max time increment, and as a fixed user-defined time increment, and for both options my model reverts to a time increment size of 0.001 instead of 1E-06
 
Abaqus/Standard automatically adjusts the size of the load increments so that it solves nonlinear problems easily and efficiently. You only need to suggest the size of the first increment in each step of your simulation. Thereafter, Abaqus/Standard automatically adjusts the size of the increments. If you do not provide a suggested initial increment size, Abaqus/Standard will try to apply all of the loads defined in the step in the first increment. In highly nonlinear problems Abaqus/Standard will have to reduce the increment size repeatedly, resulting in wasted CPU time. Generally it is to your advantage to provide a reasonable initial increment size (see Modifications to the model, for an example); only in very mildly nonlinear problems can all of the loads in a step be applied in a single increment.
