Elemental concentrations are accurately specified. Assimilation efficiencies are the same for all sources and elements. Solutions within solution polytope are equally likely. No variance in isotope ratios in sources. No variance in elemental concetrations in sources. No variance in assimilation efficiencies. ... 17.323 Set random seed = 25057 ... 17.325 Draw 0 samples from MVN isotope distribution ... 17.42 Plot Augmented Convex Hull ==> process Mixture: BrownSym ... 22.678 Draw uniform samples from convex solution polytope Drawing 1 sample(s) of size 10000 for a total of 10000 samples: 1 Unique Solution ... 22.801 1 of 1 = 100 % of mvn samples lead to feasible solutions ... 22.803 Back-solve from biomass to isotopes contributions ... 22.805 Display mariginal histograms and Numerical summeries and Write out samples ==> process Mixture: BlackSym ... 22.898 Draw uniform samples from convex solution polytope Drawing 1 sample(s) of size 10000 for a total of 10000 samples: 1 WARNING: Encountered an Unfeasible Solution -- check Convex Hull plots. ... 23.04 0 of 1 = 0 % of mvn samples lead to feasible solutions CRITICAL: No feasible solutions.
