I wonder if you have included the <CONDITION> section in your cylinder1_Spherigon.xml file? Or is there another file with the information about boundary conditions that you would normally use when running the simulation. I think this error may reflect that it is trying to find the boundary 1 (i.e. bnd=1) but it is not defined since this information is not included in the xml file you have provided?

It should be fine to use the ending chk it is treated just the same as fld

Cheers,

Spencer.

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
