MCT File Output

Output details of the analysis to the .mct file.

For large analyses it can be advantageous to know the specific point in time at which the first damage occurs. You may also be interested in the number of failures that have occurred. Using the following keyword in the HIN file will activate output to the .mct file for the entire analysis:

*OUTPUT, FIRST DAMAGE=YES/NO, DAMAGE ACCUMULATION=YES/NO
DTIME

If the FIRST DAMAGE parameter is set to YES, the following will be written to the .mct file:

• Step number, increment number, and analysis time when first matrix damage initiates within any Helius PFA material.
• Step number, increment number, and analysis time when first fiber damage initiates within any Helius PFA material.

If the DAMAGE ACCUMULATION parameter is set to YES, the following will be written to the .mct file:

• At the end of every converged increment, the total number of integration points that contain a matrix failure.
• At the end of every converged increment, the total number of integration points that contain a fiber failure.

If DTIME is given, the damage accumulation output will be restricted to time increments of DTIME. For example, if DTIME is 0.1 and the full analysis runs to 1.0 with increments of 0.01, the damage accumulation will be output at times 0.1, 0.2, 0.3, etc. This is useful for limiting the output in explicit analyses which contain very large numbers of increments.

The *OUTPUT keyword may only be used once in a HIN file. The keyword applies to all steps of an analysis.
