give me solution, i can perform buckling analysis in ansys workbench 14.5, it will shows the errors. kindly help me
1. it will comes the error At least one body has been found to have only 1 element in at least 2 directions along with reduced integration. This situation can lead to invalid results. Consider changing to full integration element control or meshing with more elements. Refer to Troubleshooting in the Help System for more details. and
2.One or more contact regions may not be in initial contact. Check results carefully. Refer to Troubleshooting in the Help System for more details.
3.Solver pivot warnings have been encountered during the solution. This is usually a result of an ill conditioned matrix possibly due to unreasonable material properties, an under constrained model, or contact related issues. Check results carefully.
4.An unknown error occurred during solution. Check the Solver Output on the Solution Information object for possible causes.

1 and 2 are relatively easy to fix, and will probably make 3 and 4 go away

1- Refine your mesh to add more elements for whichever part has only one element along a face
2- Parts that you have specified contact for are not starting in contact. Update your model to move them closer together initially if possible or just make sure they are behaving properly in your results (i.e. no penetration etc)
