Dear Wang,<div> To the best of my knowledge there is not any other way..But you can try increasing the smearing parameter.. This will help in convergence but I dont know whether it will solve your problem or not...<br>

Dear MOHNISH<br><br>First, thank you very much for your advices. The initial crystal structure were referenced to the experimental value. Using the vc-relax calculation is to find the structure with minimum energy for Raman frequencies calculation. Beside the change of the initial lattice parameter and atom position, is there another means to solve the case such as changing some threshold value?<br>
