Dear nektar users,
I am exploring my 3D dns data computed by nek5000, and hoping it would be used for stability analysis. I found nektar++ could read nek5000 binary field
directly in the technical document
http://doc.nektar.info/latest/class_nektar_1_1_field_utils_1_1_input_nek5000.html
I run FieldConvert -l, and it gives
Available classes:
Input: bse:
Reads stability base-flow file.
Input: chk:
Reads checkpoint file.
Input: dat:
Reads Tecplot dat file for FE block triangular format.
Input: fld:
Reads Fld file.
Input: fld5000:
Reads Nek5000 field file.
.................

I firstly generate a cubic.xml file and then build a new nek5000 dns setup with exactly same coordinates. Then run it in nek5000 to obtain a sequence cubic0.f00001,.... cubic0.f00025 fields.
Next, I defined the binary nek5000 data ( e.g. cubic0.f00025) as the restart file. When I run nektar, it gave an error, as below

Did I miss something? or can someone help me? thanks!
