Hi
I modeled concrete walls as wide columns with rotated axes, as shown in the attached image from the preprocessor. After running the simulation, these wide columns appear rotated in the postprocessor (see the second attached image). I’m not sure why this is happening. While the gravitational results are correct, I'm concerned about potential issues with the seismic dynamic non-linear analysis. Can you help me understand what’s going on? Thanks in advance.

It should be just a visualization issue. The mpco recorder cannot save the local axes of elements , so stko reads them from the auxiliary file mpco.cdata, which is created by the stko pre processor when you write the input tcl files. Make sure to have those files
