Hello everybody, nI'm performing a thermo-mechanical fatigue analysis with ansys workbench. nI wanted to ask if there is a way to perform the following with ansys workbench: nApply one load cycle (displacement and temperature)nRead an output variable which I defined (damage) nIf this variable is lower than a defined maximum value, then repeat the load cyclenIncrement a cycle counting variablenRepeat till the damage reaches a maximum value that I define. nIs this something feasible with workbench?Thank you very much for your help! n

Probably not. How are calculating the output variable? Are you calculating it using the Mechanical Fatigue Tool (FT) or are you calculating it using MAPDL commands?n

[alessandra.grandinetti]

the output variable is calculated through a dedicated script in fortran. n

You would need to write an ACT extension to drive this analysis or drive it using MAPDL commands in a Command Object. You could transfer the model to MAPDL and use it.n
