Hello, I'm having trouble running my simulation. The following message is appearing: "Failed to update the Solution component in CFX. The solver failed with a non-zero exit code of: 1". I'm analyzing wind loads on buildings, and I'm currently performing a wind load at a 90° angle to the building. However, the error keeps appearing during the simulation, and I don't know how to solve it anymore. I've already tried renaming the files, uninstalling and reinstalling Ansys. I'm using the student version for the analysis.

Below is a Google Drive link to access the project.

Please, i need help!!!
