Dear sir,<br>I intended to run some calculations of a system having hexagonal crystal structure and 5 atoms in the unit cell. I have generated the correct structure (visualized with Xcrysden) with the StructGen tool of WIEN2K . But in the <b> </b><font size="-1"><b>initialize calc.</b> step, after <br>
<font size="-1">doing </font> </font> <b>x dstart , </b>an error or warning (?) <b>: probleme mit log. ableitung </b>is coming<b>. </b>I am not able to understand this sentence. If I proceed with that, the calculations (scf or optimization) stop giving the following errors,<br>
