The user cannot edit the generated balance equations!<br \/>Add algebraic equations (the so-called Constitutive Relations) to the model definition, such as transfer laws, kinetic rate expression, geometric relations, state variable transformations, etc. The dynamic balance equations and the algebraic equations, which are placed on top of the physical topology and species topology, represent the <strong>equation topology<\/strong>.<br \/>&nbsp;\n      <\/div>\n<div class=\"inline page-text methodology-images\">\n         <img decoding=\"async\" src=\"\/web\/wp-content\/uploads\/2017\/11\/Mobatec-Modelling-Methodology-Equation-Topology-Small.jpg\" onclick=\"imageLightBox(this.src)\">\n      <\/div>\n<\/p><\/div>\n<div class=\"methodology-step-wrap\">\n<h3 class=\"page-subtitle\">Step 4: Control Scheme<\/h3>\n<div class=\"inline page-text methodology-images\">\n         <img decoding=\"async\" src=\"\/web\/wp-content\/uploads\/2017\/11\/Mobatec-Modelling-Methodology-Control-Scheme-Small.jpg\" onclick=\"imageLightBox(this.src)\">\n      <\/div>\n<div class=\"inline page-text methodology-desc\">\n         Add the (dynamic) behaviour of the information processing units, such as transmitters, adjusters and controllers.<br \/>&nbsp;\n      <\/div>\n<\/p><\/div>\n<div class=\"methodology-step-wrap\">\n<h3 class=\"page-subtitle\">Step 5: Dynamic Simulation Run<\/h3>\n<div class=\"inline page-text methodology-desc\">\n         Perform a simulation run: interact with the model, plot any variable, export data, etc.<br \/>&nbsp;\n      <\/div>\n<div class=\"inline page-text methodology-images\">\n         <img decoding=\"async\" src=\"\/web\/wp-content\/uploads\/2017\/11\/Mobatec-Modelling-Methodology-Dynamic-Simulation-Small.jpg\" onclick=\"imageLightBox(this.src)\">\n      <\/div>\n<\/p><\/div>\n<\/div>\n<div id=\"lightbox\" onclick=\"document.getElementById(this.id).style.display='none';\">\n<div id=\"lightbox-content\" onclick=\"event.stopPropagation();\"><\/div>\n<\/div>\n<p><script src=\"\/web\/scripts\/lightBoxControllers.js\"><\/script><\/p>\n","protected":false},"excerpt":{"rendered":"<p>&nbsp; Modelling methodology implemented in Mobatec Modeller is based on the hierarchical decomposition of processes (in which material and energy exchange are playing a predominant role during normal operation) into networks of elementary systems and physical connections.
