I try to solve a simple task to solve in Altair Inspire, but it is always canceled with "optimization error #1755". What's wrong?

    when you go to the 'run status' window, and RMB in the model name, there's an option of opening the project folder.

    The you should find a .stmod, and a few files. If there's any .out file you can share it here. The .stmod would be also useful.

    Hello Mr. Koga,

    unfortunately, it seems there is no .out file in the folder. I share the .stmod file...

    your Boundary Conditions (SPC) are all free to move, in all directions.

    So you will have free body movement.

    Please correct it and run again.

    From the .out file in the running folder, it shows you this.

    Thanks a lot,

    I think that green marked directions are fixed and others are free. Now it is clear where is the problem...
