[AMBER] gbsa parameter

Greetings,

The 'gbsa' parameter is set to 0 by default and when I set it to 1 or 2,
the GB simulations as slowed down. Is the SASA calculation necessary,
namely have the igb=1, 2, 5, 7 or 8 been optimized using gbsa=0 or not?

Another question. OpenMM calculates by default the SASA using the "ACE
approximation". Should I turn this feature off to get consistent results
when I run GB simulations with AMBER .prmtop files (provided I used option
gbsa=0 in AMBER simulations)?


​thanks in advance
Thomas
