# EnergyPlus simulation failed after version converting

Dear all, I updated the mid-rise apartment prototype model from DOE website from version 8.0 to version 9.1. After that, when I run the model, I got severe errors like:

   ** Severe  ** checkSubSurfAzTiltNorm: Outward facing angle of subsurface differs more than 90.0 degrees from base surface.
**   ~~~   ** Subsurface="TWINDOW14" Tilt = 90.0  Azimuth = 270.0
**   ~~~   ** Base surface="T EWALL C" Tilt = 90.0  Azimuth = 90.0


Please let me know if you have any suggestions. Thank you

To provide some help, can you confirm the models were downloaded from https://www.energycodes.gov/developme... and which standard/code, year, and climate location did you use? Thanks

Please try to change the vertices of three surfaces to what's shown below, the errors should be fixed.

sorry, I just changed the answer to "preformatted text" to make it easier to see.
