<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;"><DIV>Hi all,</DIV>
<DIV> </DIV>
<DIV>I am trying to optimize a Ru3----H2 cluster, where the Ru3 is an equilateral triangle in the xy plane and H2 is along the z axis and collinear with the centroid of Ru3. While optimizing, I am freezing the Ru coordinates, and using cartesian cooordinates for all the atoms. Here is my geometry specification:</DIV>
<DIV> </DIV>
<DIV>geomtyp=xyz<BR>geom={nosym;noorient;angstroms;<BR>5<BR>ru3-h2 dft<BR>H1 a1 b1 c1<BR>H2 a2 b2 c2<BR>Ru3 a4 b4 c4<BR>Ru4 a5 b5 c5<BR>Ru5 a3 b3 c3<BR>}<BR></DIV>
<DIV>After I submit the job, I keep getting this strange error in the output file:</DIV>
<DIV> </DIV>
<DIV>Possible error in geometry specification<BR> The centres 3 RU3 and 1 H1<BR> have ended up at the same place<BR></DIV>
<DIV>Could anyone please tell me why it is doing that. Thanks guys.</DIV>
