[molpro-user] restriction on active orbitals in CASPT2

[Ilya Ioffe]

Dear MOLPRO team,

I tried to do a CASPT2 calculation (RS2 since I needed a gradient; ver. 2010.1; 64-bit SMP) and found out that the number of active occupied orbitals is restricted to 32. Could you, please, tell me, whether this is a global or version/platform-dependent restriction that may be overcome somehow?

Best regards,

Ilya
