Hello, Thanks fo the update. .dat file is empty when performing a Buckling analisys. Should I add something to get the values written there?. Regards ---

You should now get this by default from Buckling (\*BUCKLE) step: ![buckle](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/5/5dd93fbe290cc3fb592a160613ac7197bab22f0c.jpeg) ---

I can’t see it. Maybe it’s because my buckle step is a perturbation. One should not include self weight (Gravity Loads) into the buckle step as they should not scale as regular loads do. NOTE: I have reinstall, erase previous versions , create a new analisys and now it writtes the buckling factors into the dat file. Not sure if I was looking at an old working directory or reinstalling make some effect. Anyway, seems solved. 👍 ---

I have additionally noticed that prepomax don’t ask the user if he wants to save the results before closing and they are not automatically saved. ---

Can you report the step by step instructions on how to reproduce the problem? ---

I’m not sure yet if I was looking at an old working directory, reinstalling made some effect or if saving updated the .dat. I will pay more attention if it happens again.
