Hi How can i load Mesh file from Gambit to C++ ? with all Node,Element,Boundary !!!

save the mesh file in text format (in Gambit it is called nuetral format)

I know that, but my problem is: how can i read that with C++?? with what operation,function & how ???

You can use the C++ input stream cin or the usual C-functions.

can u explain it more ? i read it like this (C++): fstream infile("Grid.txt");

and after that i use two 'for' loop for X&y, but it didn't work !!!

Try

ifstream infile("Grid.txt");

infile >> x; infile >> y; // etc.

i found it but iused with

FILE* f; f=fopen("filename"; scanf(f,"r");

it's read one line ...
