Dear all,

When I run the command:

FieldConvert -m extract:fldtoboundary=1 cylinder1_Spherigon.xml cylinder1_Spherigon_5.chk cylinder1_Spherigon_5-boundary.chk

It gives out errors:

Fatal : Level 0 assertion violation

Variable index out of range.

libc++abi.dylib: terminating with uncaught exception of type ErrorUtil::NekError: Level 0 assertion violation

Variable index out of range.

Abort trap: 6

I want to know can this command run with .chk file? Since we use the parallel computing, our cylinder1_Spherigon_5.chk file contains several .fld files and one info.xml.

Also I want to know for the command in Page 84 of user-guide-4.4.1,

what does "bnd" really mean?

Could you help me figure this out? Thank you very much!

Best,

Shan
