Regarding the fatigue analysis of pressure vessels, ANSYS is used for load step solution. . . .

Thread Content

A certain device experiences pressure fluctuations and temperature fluctuations; fatigue analysis is required, with the results obtained under the two operating conditions being subtracted from each other. The Ansys file is named pl.db Time1,,,,,,,,,,,,,,,,,,,,,,, Then, run solve, and then save it. Is this save done to pl.db? During Time2, when parameters such as temperature, pressure, and material properties are changed, can the /clear command be used? Is it possible to erase the results from Time1? If the /clear command is not used, does it mean that all loads, the model, and cell properties must be deleted before proceeding to Time2? Please guide me through the solution process, thank you
