By default, a single moisture environment is used throughout the analysis. This environment is determined by the MOIST field of the MATPFA keyword for ANSYS. You can use the HIN file to define a unique moisture content for each step of the analysis.
*STEP, NUMBER=N, MOISTURE=AMBIENT/DRY/WETwhere N is an integer that corresponds to a step in the input file. Select AMBIENT, DRY, or WET to define the moisture condition for the step. You may repeat the *STEP keyword to define a unique moisture condition for every step of the analysis. The moisture condition selected for a given step is used for the remainder of the analysis, unless explicitly changed for the next step.
Consider the example below, where we want to use AMBIENT material properties to simulate the cure cycle and WET material properties to simulate the mechanical loading:
*STEP, NUMBER=1, MOISTURE=AMBIENT
*STEP, NUMBER=2, MOISTURE=WET
