Dear Wien2k users, I am also certain that I am not doing any mistake in the formula of Volume=a^2 c Sin 60. However, the V0 printed in the window showing the fitted BM curve is coming much less than that expected from a^2 c Sin 60 . What could be the cause? Is it

Dear Lyudmila Sir, To remove the confusion I am sending the struct file which have been used in our simulation. I have good results as far as the volume optimization curve is concerned. However, while calculating the lattice parameters using the formula V = a^2 c sin60 I

Dear Wien2k users, I have started volume optimization of S using a cif file attached herewith using nlvdw. The simulation goes well and presented a minima in the volume vs energy curve. However, when I opt for the calculation of unit cell volume for R_3 (space group no.
