The following briefly describes the menus for the Macintosh version of the HYDRA2D
application.
The program may be interrupted at any time by clicking the mouse button.
File:
OPEN: not available in this version.
SAVE: not available in this version.
QUIT: exits program.
Microstructure:
ADD C3S PARTICLES: adds the number and size of C 3S particles as designated by the NUMBER and SIZE menus
ADD FILLER (REACTIVE): adds single pixel reactive filler particles with reactivity designated by the Pozz menu. The number of particles added is designated by the selection from the Number menu.
ADD FILLER (INERT): adds single pixel inert filler particles. The number of particles added is designated by the section from the Number menu.
ADD AGGREGATE (REACTIVE): places a single reactive aggregate particle in the center of the image with width from the Size menu. Note: a size selection of 1 will not produce an aggregate.
ADD AGGREGATE (INERT): places a single inert aggregate particle in the center of the image with width from the Size menu. Note: a size selection of 1 will not produce an aggregate.
MOVE PARTICLES: allows the movement of C3S particles toward the aggregate. Particles are moved pixel amounts designated by the selection in the Size menu.
MEASURE PHASE FRACTIONS: displays the volume fractions of all phases present in the image.
MEASURE PHASE FRACTIONS VS. DISTANCE FROM AGG: writes the area fractions of all the phases present in the image to a file. The data is written in column format and can be imported into a spreadsheet for graphical analysis.
CLEAR IMAGE: erases current image and allows the user to start over without quitting the program.
Number: Number of particles to be placed the next time ADD C 3S PARTICLES or ADD FILLER is chosen from the Microstructure menu.
Size: This selection is used for several operations in the Microstructure menu. It is used to determine the size of the C3 S particles, the size of the aggregate, and the number of pixels that particles are moved in the MOVE procedure.
Hydrate: This menu initiates the hydration simulation. The upper half of the menu will hydrate the image the selected number of cycles, while the lower half of the menu will hydrate the image to the selected degree of hydration.
Steps: This menu selects the number of diffusion steps that are allowed in the hydration process before automatic nucleation is enforced. A high number will take longer to run and produce a more realistic microstructure.
Prob: Prefactor for exponential probability for CH nucleation. A low number will take longer to run and produce a more realistic microstructure.
Scale: Scale factor for exponential probability for CH nucleation. A high number will take longer to run and produce a more realistic microstructure.
Pozz: Pozzolanic reactivity factor of the reactive filler (e.g., 2.08).
