Problem:

When I run an analysis with AutoPIPE V8i 09.06.00.15  with JSME S NC1-PPC Piping Code and edition = 2008, the following appear when I reviewing the results:

---------------------------
Warning
---------------------------
W831-11: Seismic level includes cases not analyzed
---------------------------
OK
---------------------------

---------------------------
Note
---------------------------

Seismic case number exceeds the number of defined Seismic load cases.
---------------------------
OK
---------------------------

However, it does not appear when using year = 2005. Why is that and how to avoid?

In addition, when reviewing the code combinations, 

CODE COMPLIANCE COMBINATIONS

<Description>
Combination               Category   Method    Case/Combination
----------------------- ----------- -------- ---------------------

**i*Szy{1}      CSC Primary Abs sum *Pres          

**B*Szy{1}      CSC Pri+Occ Abs sum *Pres  

where   ** indicates that the combination includes unanalyzed load case(s)             

Solution:

See the following WIKI page: W831-11: Seismic level includes cases not analyzed
