# Interference fit problem in ANSYS Workbench 16.1 - how do I get rid of pressure/displacement raisers?

I have an interference fit problem of two perfect cylinders modelled in 2D using symmetry. The overall interface pressure is around 20MPa lower than the hand calculations and I get non-uniform displacement / pressure near the edges of the model. Any suggestions on how to remove these raisers would be greatly appreciated!

I've attached the pressure results. [

• I have been trying to get smooth pressure results from contacts for the past 10 years from ANSYS. It is still an ongoing battle. – John Alexiou Apr 18 '16 at 13:54

Another option for might be to turn on the Normal-Projected Normal option
