question: filter in laplacian

[barronh]

There is Is the purpose of the conditional below computational efficiency?

There is a conditional test that prevents the calculation of var_bin_field, var_bin_lap_field, var_field, and var_lap_field when the lap_field_2d is small.

if ( lap_field_2d(i,j) .gt. 1e-13 ) then

GENBE_2.0/src/gen_be_stage4.F

Line 356 in 549f360

if ( lap_field_2d(i,j) .gt. 1e-13 ) then

Based on testing, I don't think this conditional filter is good for chemical (e.g., no2) calculations. When I remove the filter, the results look much more reasonable.
