Hi @lihouxin065 

It is difficult to know what causes the problem from the log file.

• What type of load is applied? (The file implies that you have both a ground motion and a force. You should only apply one or the other, not both.)
• When does the error occur? Soon after the analysis starts? At the end of the analysis?
• Are you outputting all 2000 time steps? That would result in files that are over 2 GB in size. (I am not sure if Sim Mech Transient Stress supports files over 2 GB or not.) When the analysis ends, are any of the files in the DS folder over 2 GB in size?

If you do not find the solution, someone can take a look at the model if you make an archive ("app button > Archive > Create > Model Only") and attach the archive file (.ach) to the forum post.

@John_Holtz 

(1)There is  node displacement results，but no strain/stress results like(No-Stress-results-on-DDAM-with-a-high-number-of-modes-in-Simulation-Mechanical ),

(2)I run mknso.exe  from  DOS Window follow the directions on( How-to-run-a-Simulation-Mechanical-analysis-from-the-command-prompt-DOS-window ).

(3)then I get a forrt1:sever(170): progam exception-stack overflow, the mode maybe too lage(General Fortran Error Messages )

@John_Holtz the Design Scenario file is about 5 GB.
