Hi, when exporting to Abaqus .inp file from PrePoMax 2.4.0, the following keyword is written: ```auto *Buckle 1, 0.01 ``` The second number is the accuracy in CalculiX. However, Abaqus doesn’t have it, and the second item is interpreted as the maximum eigenvalue by default. This may lead to no eigenvalues being found. ---

I have fixed the problem and will release a new developer version. ---

Thanks, now it’s ok in Abaqus keywords, but becomes NaN in GUI after exporting: ![image](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/c/c9398d07b5d0d6a0a397d6df10fbff08d8d07763.png) ---

Here are the minimum steps I can use to reproduce it in 2.4.0: 1. Create a new model with default settings. 2. Switch to the FE Model tab and create a Buckle step. 3. Export to Abaqus .inp. 4. Edit the Buckle step - Accuracy should be NaN now. ---

I still cannot reproduce the problem. Are you using the released version from the download page? ---

Found it. Version 2.4.1! It is already fixed in the upcoming 2.4.2 version. ---

Great, thank you. I will test it later. ---

If this works now, can we close the topic? ---
