How can I check the stress distribution of my structure?

Sorry for using translater because of my poor english skill.
I'm running a simulation of a project to build a spaghetti bridge using ansys apdl.
The picture below is the structure I'm simulating.

In order to check the stress distribution of the structure,I follow the step below.
General Postproc-Plot Results-Contour Plot-Nodal Solu-nodal solution-stress-von Mises stress

But a error window popped up and I couldn't confirm it.
Error said 'The requested S data is not available. The PLNSOL command is ignored.
There was no problem when it was performed with a 3D model in class.
I don't know why this happens. Please Help

Hi,

Can you confirm that the OUTRES command includes outputting stress data to rst file? Did you issue the "SET" command to point to a result set before you plot? When distributed solver is used it is required to issue the SET command. Otherwise only some of the results are available in the database.
