Hello,  
I’m running a static calc. with  
\*ERROR: increment size smaller than minimum  
and i got a dataset FORC in the last timestep / result with displacement  
when i have no error, there is no dataset with FORC.  
Why i get these dataset ? what is the information of it ?  
is there a relation between (external reaction) force and the \*ERROR?

# edit

in \*NODE FILE  
the variable RF is not activated.

thnx in advance
