[SIESTA-L] no SCF convergence with Methfessel-Paxton scheme

2009-12-16 Por tôpico leila
Hi everybody, I have a simple question. When I use MP scheme(from 25 meV to 1000 meV every 25 meV incensement) with 9*9*9 (I made a test with 18*18*18 K while nothing changed) Kpoints, I can't obtain convergence in SCF steps (mixing value 0.04, 0.06 or 0.1). It is not the question of the amount

Dear SIESTA users Hello I am trying to run a test calculation for VDW XC functional in siesta-trunk but I am getting the following error: 1610022975: DEALLOCATE: memory at 0x41b7530629f23c7d not allocated for usinf VDW I only changed these lines: XC.functional VDW XC.authors

Hi Javad, Your error message says that you are trying to deallocate a variable that has not been dynamically allocated. I would recommend compiling in debug mode to see the *specific line and routine* where the deallocate command is called. Then you should be able to get into the offending
