Problem after switching to 2024P1

      Hi all.
      Updated to ANSIS2024R1.
      I run the calculation of the k-file made in the Daina 2023P1 prepost, it worked there, but in the 2024 version it shows an error:

       

      Why? I tried removing the titles, checked all the points, everything is fine.

      Hello, 

      For some reason the line 99 is treated as a part of the *BOUNDARY_PRESRIBED_MOTION_SET_SEGMENT_ID from the line 90. Could you open the model in LS-PP and verify if all *BOUNDARY cards are property formatted?

      Please let me know how it goes.

        Everything is fine there sir.
        I noticed this strange thing. If I manually remove the SPC card from the k-file and add an empty line after MOTION_SET then the calculation works.
        But this is a fatigue analysis based on a calculation that has already been carried out. And if this is not an analysis for fatigue, then there will be no fastening and the part will fly away.
