How to model initial geometric imperfections in model based on buckling modes

You must first select the mode in the solution, then go back to the modeler and use Transfer displacements from solution in the Mesh tools menu. The active mode will be transfered
You will be asked to provide a scale factor in the process.

It is important that your buckling shapes solution is OUTPUT2D. This way the solution and geometry will have the same number of nodes.
Output 2D is a ccx custom card.

NOTE:Once you finished to transfer the imperfections save the file with different name to keep your original buckling analysis file clean and with the original mesh.

I forgot to mention Output2D is required if you are modeling with shells as they are expanded.
With solids is not needed.
