So isses - bei mir zumindest...

Normal Stiffness
Defines a contact Normal Stiffness factor. Property options include:
Option
Description
Program Controlled
This is the default setting. The Normal Stiffness Factor is calculated by the program. If only Bonded or No Separation contact exists, the value is set to 10. If any other type of contact exists, all the program controlled regions (including Bonded or No Separation) will use the Mechanical APDL application default (Real Constant FKN).
Manual
The Normal Stiffness Factor is input directly by the user.
Normal Stiffness Factor
This property appears when the Normal Stiffness is set to Manual. It allows you to input the Normal Stiffness Factor. Only non-zero positive values are allowed. The usual factor range is from 0.01-10, with the default selected programmatically. A smaller value provides for easier convergence but with more penetration. The default value is appropriate for bulk deformation. If bending deformation dominates, use a smaller value (0.01-0.1).
For additional MAPDL specific information, see the Determining Contact Stiffness and Allowable Penetration section of the Mechanical APDL Contact Technology Guide (Surface-to-Surface Contact).
