Hello Support, I runned a coupled thermal displacemente analysis in transient mode. The calculation finished correctly and I have obtained the results. I have a .frd file of 13 Gb, the problem is that when I got to red this file with Prepomax version 1.3.5 I obtain the error that you can see in the attachment

Try with a newer version (possibly the newest available one). Issues with large .frd files were recently corrected.
