Problem with Optistruct ASCII Output (Displacement)

greiffith tanzal_21385

Hi Everyone,

I have questions regarding the ASCII output file from an Optistruct simulation.

So from this website (https://2021.help.altair.com/2021/hwsolvers/os/topics/solvers/os/disp_file.htm) I figured out, that the displacement (force, stress, etc) can be written out in ASCII Format using the OPTI Format under each load case (or maybe in the Global Output Request cards for all Load Case). 

For that, I created a timetable using SET_TIME, assign this SET_TIME into the Output parameter (NLOUT), and assign this NLOUT in the Load Case. (I put some Pictures of my parameter settings). 

 

 

 

so I would like to get the Displacement data at one node in ASCII Format. The result I'm expecting would be something like this

But what I got is something like this

I wonder where are the mistakes, can anybody please help me? 

Best regards,

Greiffith

Hi Greiffith,

The displacement results for this node are written out at different intervals specified in the NLOUT option with the NONLINEAR LOAD FACTOR. I hope this reference on the created .disp file helps, it includes rotational components as well.
