[Nek5000-users] Read Nek output in Matlab

Alessandro,

Set, in usrdat2 in your .usr file the following lines:

      param(66)=0
      param(67)=0

this will give you an ascii file output.  blah.fld01  blah.fld02 etc

You can edit these files or write a short script to take off the header or
whatever and then load the data into matlab.

Usual data lay out (for 2D) is:

x y u v p T

for fld01

and 

u v p T

for all other fields.

Paul

Subject: [Nek5000-users] Read Nek output in Matlab

Hi Neks,

I would like to make some postprocessing with the Nek output. Can I read
that files in Matlab (or C)?

Just to make it clear: If my .rea file is called whatever.rea and the
output is whatever0.f00****

I would like to read whatever0.f00**** and make some postprocessing. It
will be also very helpful to learn how to extrapolate the mesh so that I
can plot combinations of the solutions for instance.

Thank you so much,

Alessandro
