Many thanks Frédéric. It works indeed. Here are some line codes for people interested :

fespace Vh(Th, P2);  
Vh c, ctest;  
// copy the data c into a vector  
ctest= c;  
// save the P2 FE field  
{ofstream ff(“csol.txt”); ff \<\< ctest\<\< endl;  
}  
read the P2 FE field  
{ifstream gg(“csol.txt”); gg \>\> ctest3;  
}  
// plot the read data  
plot(ctest3, Th, value=true, wait=true);
