I’ve been trying to get cubeprop to calculate an electrostatic potential for me as is done here, using essentially the same input.dat except with set df_basis_scf cc-pvdz-jkfit substituted for set df_basis_scf cc-pvdz .
When I run this, though, I get a the following error:
RuntimeError:
Fatal Error: Auxiliary basis is required for ESP computations.
which originates from the csg.cc source file.
I went to the code to try to figure out what I was doing wrong but it’s unclear to me. Clearly auxiliary_ needs to get bound to the CubicScalarGrid object created in the cubeprop call, but I can’t figure out where this would happen if it’s not being done at the time the CubeProperties object is initialized. grepping the source files for set_auxiliary_basis (in csg.h) gives us fisapt.cc, which calls this manually in its plot function.
Does anyone know how I can either 1) set this manually in my input.dat file or 2) set some global option that will configure this automatically?
