Routine to create *chk
Dear all, Does anyone know how to load *vtu files by. nektar++? Or the rules to export the binary check file *.chk? Thanks, Regards, Wei
Hi Wei, Not sure this is what you ask for, but: I do not think you can load the *vtu file in to Nektar++, this is a Paraview file, right? If you want to export the result as a binary file you can use the *plt format, which is Tecplot, but can be read by Paraview if it is compiled with VisIt readers.

Hi Stan, Thanks! What I want is how to convert *vtu file into *chk. This need the subroutine of generating the *chk. I am not clear the format of *chk. Regards, Wei

Hi Wei, Since *.vtu files are VTK unstructured grids, primarily used for visualisation, we do not really have an existing method to convert them back to the native Nektar++ field file format. VTK files are usually generated from Nektar++ output files using the FieldConvert utility. As Stan mentioned, VTK files can be loaded and manipulated in Paraview. Could you give us a little more detail what you need to achieve and hopefully we can help steer you in the right direction?

Hi Chris, I am planing to do data process without using nektar++ utilities. Assuming that I run a dns simulation using a incompressible solver, then a handful of *chk files will generated. Since the chk file is not written in ascii, it is hard to identify the data structure. If I know the rules to control the stream of generating chk files, then I will manipulate the *chk directly and efficiently and then convert the new chk into vtu or tecplot format by nektar++ as normal.
