Dear all,<br><br>As First, Thank you to all helping me in previous questions. I have some basic doubts in extending QHA calculations.<br><br>1) Is QHA implementation with pwscf is up to primitive orthorhombic only??? Now i want to calculate QHA properties for body centered orthorhombic structure. Recently i have seen several literature for different crystal structure. please suggest me in that point<br>
<br>2) I want to calculate lattice parameters, bulk modulus w.r.t Temperature , Thermal expansion coefficient and Grunessian parameter using QHA. Is there any tutorial or basic i/ps for those calculations???<br> If possible please explain me for cubic structure.<br>
<br>Thanks in advance<br><br>with regards<br>S.Appalakondaiah<br>Research scholar <br>University of Hyderabad<br>India<br>
