The values in the spatial structure are irrelevant; all physiological parameter values will be overwritten when importing the simulation in PK-Sim as population simulation (see tutorial). Basically, the spatial structure BB is only used as dummy model structure that has more compartments than the PK-Sim standard model structure and the physiological values of this dummy model are only placeholders.
Unfortunately, the pregnancy model structure cannot be combined with pregnant individuals in PK-Sim (only with populations) which may blow up computation time, but the new R toolbox allows this :)
That means that the parametrization in MoBi does not really make sense? How do you do model development, then? There is no way e.g. to run PI with populations, right?
Model development is typically done in adults and once the model is adequate it is extrapolated to pregnancy by exchanging the spatial structure/passive transport BB (MoBi) and by parameterizing the physiology according to pregnancy stage (population import PK-Sim). That is possible. Model development starting specifically with a pregnant individual is not possible, though, and running a PI with a pregnancy model is neither possible (unless all parameters are correctly defined in MoBi).
However, since the pregnancy model does not involve hundreds of physiological parameters that are different from the adult ICRP model, a workaround could be to e.g. calculate the relevant parameter values in R (e.g. by using the R toolbox), write these values together with the parameter path in a table and import it as PSV in MoBi.

@AndreDlm Can you explain this?
