How to solve "Geometric correction data seems to be inconsistent"-Warning? 1

Hello there,

today I had a "problem" with a model using imperfections and general contact in Abaqus standard. When I do not use the *imperfection keyword, there are no major warnings in my model. But as soon as I add imperfections, I get the warning message: "THE GEOMETRIC CORRECTION DATA SPECIFIED FOR THE SURFACE ASSEMBLY__General Contact_gcs0_470 SEEMS TO BE INCONSISTENT WITH THE ORIENTATION OF THE ELEMENT FACES INCLUDED IN THE DEFINITION OF THIS SURFACE. PLEASE VERIFY THE CORRECTNESS OF THE DATA." for every surface assembly involved. Leading to hundreds of warning messages.

I have never had this warning message. Why does it occur and how can I solve it? How can I check the orientation of the element surfaces? The models do converge and behave as expected. The results seem reasonable (I don't have any real experiment to calibrate them, though), but this still bothers me.

Any tips? :)

Sometimes warnings in Abaqus seem to indicate serious problem and yet they can be ignored. However it's always good to try solving these issues. You can check orientations (normals) using Query tool or plot it in the output database since you already have results.
 
Thank you for the fast reply! Maybe I should have mentioned, that I am using C3D8R elements. To be honest, I have no idea what I could actually do about the orientation of their element faces (if they were wrong)?! With shells, I'd know what to do, but not in this case. Could you explain that in more detail?

Thank you for your help!
 
Do you have contact surface smoothing enabled ? If yes then try running the analysis without this option. It may not work properly when imperfections are used.
 
You were right about the surface smoothing. That was the reason. However, I made a calculation with and without surface smoothing and the results were the same. So, my results so far shouldn't be negatively affected.

Thanks again!
