Updated Figures can be seen in Complex_subgrid_figures.pdf. See discussion below. ------- Response to query for differences between V2.3.2 and V2.3.3 From Zora Dash to Ian Nienhueser May 2011 The latest version of PLUMECALC corrects the subgridding issue identified by Dennis Fryar. The problem was found when using subgridding in PLUMECALC V2.3.2 on a simple model that used FEHM streamline particle tracking with dispersion. The problem of over estimating the concentration was identified as an implementation issue related to when the delay applied due to diffusion was computed. In the original implementation of mobile concentrations, the time delay was calculated before any subgridding occurred. This lead to an over calculation of concentration no matter what level of subgridding was used. This problem has been corrected by doing the time delay calculations after the subgridding. See subgrid_problem.doc ------- This version also implements a modified integration scheme for the source term function. We identified problems in the numerical integration scheme when small decay constants were used, especially if the source term wasn't constant but was increasing or decreasing. I have rerun all of my test cases and found that there are only minor differences in results due to the modified integration scheme. Test cases were rerun with this version V2.3.3. Of particular interest are the test results associated with the complex grid subgrid example documented in Sections 6.3.2 and 6.3.3 of the Users Manual (Dash et al, 2011) Figures 32 to 39 (and specifically Figures 35, 37, 38 and 39). With exception of the case run with both dispersion and diffusion, as expected, there are no visually discernable differences.
