The Modular Program Constructor (MPC) has been designed to work with JSim's Mathematical Modeling Language (MML). MPC is a pre-compiler written in Java. It reads an input file, FileName.mpc, and generates an output file, FileName.mod, a JSim model file. The input file combines MML with “directives” embedded as comments and is able to utilize code from other JSim model files and constructed code libraries. The directives all begin with “//%” so they are comments. Directives control the identification, fetching, relabeling of variables and parameters, and assembling and recombining code into new equations. MPC currently has thirteen directives: (1) //%COM (comment directive not copied to final model file) (2) //%START codeBlockName (3) //%END codeBlockName (4) //%INSERTSTART codeBlockName (5) //%INSERTEND codeBlockName (6) //%STARTDELETE (7) //%ENDDELETE (8) //% continuation, used only with GET, REPLACE, and COLLECT directives (9) //%GET Model.mod codeBlockName (“oldName1=newName1”, ...) (10) //%SETGLOBALVAL %replacer%=("replacement") (11) //%REPLACE %replacer%=(“replacement1”, ... “replacementN”) (12) //%ENDREPLACE (13) //%COLLECT(“variableName”) Download the presentation and draft paper for details (below). Project file contains the ODE generated version of the diffusion equation using the SETGLOBALVAL directive and finite difference approximation and compares the result with the PDE solution. (Run setglobalval model). Project file shows an ode model of a transporter between two compartments and a pde model of a four species transporter both generated using much of the same code. (run getODE and getPDE; run Loops on getPDE to explore the effect of cold substrate on the outflow of tracer substrate.) Final three models illustrate generating models sequentially to build reuseable models of increasing complexity to simulate an organ-level model with heterogeneous flow for two substrates. The models are: BTEX30: a three region model (capillary, interstitial fluid region, and parenchymal cell) with flow, diffusion, exchange between regions, and consumption for single metabolite A. (Plotted on BTEX30plotpage.) The following two models are plotted on plotpages with prefix B30. BTEX30A2B: two copies of BTEX30 for two species with enzymatic conversion of metabolite A to metabolite B in parenchymal cell. BTEX30A2B10paths: a copy of BTEX30A2B is modified removing the flow declaration. A ten flow path model is generated combining 10 copies of the modified BTEX30A2B model with the multiflow algorithm.
