the CG solver makes the contacts very sticky, even if I set them to  
"perfectly sliding". How is that?

The SOR solver returns with an "lambda error" of about 1e+4. The CG  
solver returns with an error of 1e-8. (Both with a setting of 100  
When I set the iterations to 1..5, the CG solver produces "slippy  

Is it necessary NOT to solve the system of equations precisely?
