I am trying to enter some data points for the SN curve of a custom material. I have created a fatigue study and right clicked on my part and selected to edit the material. In this window there is a fatigue tab, as shown below. I have entered my data into the table and saved it, then presses Apply, but once I press apply it seems to do nothing. The window changes to "Select a material to Apply/Edit", yet all the materials are greyed out. If I try to run the study it tells me I am missing SN data. Has anyone had this before and know what to do?
