Could you please clarify whether dielectric (and kappa) maps in APBS are activated or not?.
I was trying to test this facility. Initially I did a simulation with zero ion concentration and saved kappa and dielectric maps . Then I made all the elements in the dielectric maps identically equal to one and the kappa map was left as is( was trying to see whether the o/p potential changes by a factor of 78.5, ie simulating an ion in air and water). But surprisingly, the output potential was exactly the same as the previous one!.
Could anyone please tell me what was wrong in the procedure?. I am using APBS 0.4 ( All the three dielectric maps and the kappa map was provided as input for the simulations).
Thanks a lot in advance,
