This results in a CPASSERT failed error. If I use the following coordinates, I don't get this error: C 6.92 5.00 5.00 S 5.35 5.00 5.00 O 8.10 5.00 5.00 These are the relaxed coordinates, but rounded down to 2 decimals. What causes this issue and how can I circumvent it? Many thanks for the help! With kind regards, Bram -- You received this message because you are subscribed to the Google Groups "cp2k" group.
