The following briefly describes the menus for the Macintosh version of the MERCURY two-dimensional intrusion application.
The program may be interrupted at any time by clicking the mouse button.
File:
OPEN: read in file saved as a continuous line of single byte integers representing either porosity (0) or particle (1).
SAVE: saves current images in the same format as described above.
QUIT: exits program.
Execute:
ADD PARTICLES: add the number and size of particles as designated by the Number and Size menus.
VOLUME FRACTION: displays the volume fraction of particles currently present in the image.
INTRUDE FROM TOP: performs the intrusion algorithm from the top of the image. Intrusion is performed from the maximum meniscus to the minimum meniscus as selected by the respective menus.
INTRUDE FROM LEFT: performs the intrusion algorithm from the left of the image. Intrusion is performed from the maximum meniscus to the minimum meniscus as selected by the respective menus.
INTRUDE FULL: performs a complete intrusion from all four sides of the image. Intrusion is performed from the maximum meniscus to the minimum meniscus as selected by the respective menus.
RETURN MICROSTRUCTURE: after intruding an image, the original particle image may be returned by selecting this item.
CLEAR IMAGE: erases image and allows the user to start over without quitting the program.
Number: Number of particles to be placed the next time ADD PARTICLES is chosen from the Execute menu.
Particle Size: Size of particles to be placed the next time ADD PARTICLES is chosen from the Execute menu.
Min meniscus: Minimum intrusion diameter.
Max meniscus: Maximum intrusion diameter.
Seed: The random number generator is originally seeded from the computer’s internal clock. Repeatable exercises are possible by selecting one of the three seeds provided under this menu. Each selection of Seed will reset the random generator to either the clock, or one of the three optional seeds provided.
