Hello ANSYS Forum Community,

 I hope this message finds you well.

 I am currently encountering some challenges with ANSYS simulations, and I'm seeking guidance on the most appropriate forum or platform to post specific error messages for assistance in resolving them.

 Could you please direct me to the appropriate section or method for posting error messages along with relevant details about my simulation setup? I believe that sharing these messages with the community will provide valuable insights and contribute to finding effective solutions.

Your assistance and expertise in navigating the ANSYS support channels would be highly appreciated. If you have any recommendations or if there's a specific procedure to follow for sharing error messages, I'm eager to learn and engage with the community to address these challenges. Thank you in advance for your time and assistance.

see below for an error message example

Best regards,

Hi Charles, Can you please give some more information about this? Which version are you using? Which OS? When exactly do you get this error?
