Hello Everyone,

When I run a nonlinear calculation, the process file has a warning,  as follow:

‘A reference moment value times the tolerance is used by the 
Newton-Raphson method for checking convergence. The calculated 
reference MOMENT CONVERGENCE VALUE = 1.938411291E-@3 is less than a 
‘threshold. This threshold defaults to 1.0-2 or is specified as MINREF 
‘on the CNVTOL command. Check results carefully. 

My assembly model has a lot of frictional contacts. This warning is whether or not the cause of contacts ?  

Also the warning let me to check results caerfully, and how to determine ?  

Thank you!
