3. "Y"
4. DATASETAUXDATA Common.VectorVarsAreVelocity="TRUE"
5. ZONE T="fluid"
6. STRANDID=0, SOLUTIONTIME=0
7. Nodes=25, Elements=16, ZONETYPE=FEQuadrilateral

file = 'tec.txt';
fid = fopen(file,'r') ;
for i  = 1:7
    str = fgetl(fid) ;
end
fclose(fid) ;
p = regexp(str,'\d+','match') ;
iwant = str2double(p) ;
Nodes = iwant(1) ;
Elements = iwant(2) ;
