Hello,

 I have two questions:

 First question:

 When I use Riks method for a structure that is subjected to a distributed pressure load, I get this warning:

 WARNING: The node/nset None assigned under *STATIC,RIKS to be monitored for exceeding a maximum displacement must be an assembly-level nset. The monitoring will be ignored.

I ran the following Example: 1.2.1 Snap-through buckling analysis of circular arches, model "snapbuckling_deep" in Abaqus 6.11 documentation.

 Second question:

For the following keywords: *ELPRINT

*NODEPRINT, *PREPRINT That are written in most input files examples provided in the documentations of Abqus 6.11.1 whenever I run the input file in Abaqus I receive this warning:

 WARNING: The following keywords/parameters are not yet supported by the input file reader:

---------------------------------------------------------------------------------

*ELPRINT

*NODEPRINT

*PREPRINT

How can I fix this ?

Thank you,
