An equation-based flowsheeter
The Mobatec Modelling methodology describes processes in which systems exchange material and energy. It brings physical structure, species, equations, controls and dynamic simulation into one modelling workflow.
Start with a hierarchical decomposition of the process into elementary systems and physical connections. The way you partition the process determines the level of detail and influences model accuracy alongside the other modelling choices.
Superimpose the species and reactions on that physical structure. Mobatec Modeller then generates component-mass and enthalpy balances for each elementary system. You can inspect these protected balances and add the constitutive equations that describe your process.
This white-box approach keeps the equations and their topology visible. Add the control scheme, run the dynamic simulation and investigate the process response. Process knowledge, sound assumptions and appropriate model validation remain essential.

From process to model
Follow the Mobatec Modelling methodology from the physical structure through species, equations and controls to an interactive simulation.
Define the hierarchy of elementary systems and their physical connections.
Elementary systems exchange extensive quantities through their physical connections.
The partition determines the model's level of detail and influences its accuracy alongside the other modelling choices.
Superimpose chemical or biological species and reactions on the physical topology.
Introduce species at the model battery limits to initiate their automatic distribution through the model.
Combine automatically generated balances with user-defined constitutive equations.
Mobatec Modeller automatically generates component-mass and enthalpy balances for each elementary system from the physical and species topologies.
Generated balances help reduce errors but a user is free to inspect and change them if necessary.
Add or edit algebraic constitutive relations for transfer laws, kinetic rate expressions, geometry and state-variable transformations.
Add the information-processing units that describe the process controls.
Use transmitters, adjusters and controllers to define the control scheme and its dynamic behaviour.
Run the dynamic simulation and investigate the model's response.
Interact with the running simulation and plot model variables.
Export simulation data for further use.
Built for model development
Automate balance generation, inspect the equations and adapt the constitutive relations around your process.
Mobatec Modeller generates component-mass and enthalpy balances automatically, removing the need to write or maintain them by hand as streams and reactions are added.
Inspect the generated balances, constitutive equations and their topology. Discuss the relationships and assumptions with the people developing the model.
Add and edit the algebraic relationships needed for your process, and reuse modelling work through custom libraries.
Mobatec develops the software in house, so you can discuss your application directly with the team and tailor functionality where needed.
Build. Explore. Share.
Move from a transparent flowsheet and equations to steady-state calculations, dynamic simulations and a model you can share.
Build the model
Build the physical and species topologies, inspect the generated balances and define the constitutive equations that complete the model.
Represent the process through physical and species topologies, automatic balances and user-defined constitutive equations.
Arrange hierarchical elementary systems and their physical connections visually in the flowsheet.
Define the species and reactions in the process. Introducing species at the model battery limits initiates their automatic distribution over the physical topology.
Enter user-defined constitutive equations without writing program code; the software generates the code needed for the model.
Inspect the generated balances and user-defined constitutive relations within the combined equation topology.
Add or edit algebraic transfer laws, kinetic rate expressions, geometry and state-variable transformations.
Use automatic degrees-of-freedom checks, indications and assistance while defining the model.
Set initial values as part of preparing the model for simulation.
Generate balances for each elementary system from the physical and species topologies. The generated balances are visible but protected from editing.
Start from the supplied modelling and equation resources.
Create libraries around your own models and modelling work.
Export models for further use.
Use your own unit icons to represent equipment in the flowsheet.
Explore process behaviour
Investigate steady-state conditions and dynamic behaviour, organise scenarios and connect the model with other systems.
Use the simulation mode that fits the process question.
Run dynamic simulations in real time or at an accelerated pace.
Choose fixed or adaptive stepping for dynamic simulations.
Run simulations in locked run-time mode.
Compile and run selected parts of a model while working towards convergence.
Run scripted actions, scenarios and sequences within a simulation.
Save simulation states and use automated backtrack snapshots automatically a make points you can return to.
Reset a simulation to its initial state for another run.
Use automatic controller setup as part of preparing the simulation.
Optimise model parameters within the simulation workflow.
Turn equations or parts of the model off without a recompilation.
Connect the model with a distributed control system.
Examine simulation results through dynamic two- and three-dimensional plots.
Use OPC and TCP/IP interfaces to connect the simulation with other systems.
Work with the 2D environment and connect the model to external 3D interfaces.
Run-time environment
Pass your completed model to colleagues, clients or students through the Mobatec Modeller run-time environment. They can use the simulation without seeing how the model was built or accessing its underlying equations and modelling know-how.
Give others a working model they can use to explore the process and its behaviour. The run-time environment lets them work with the simulation you have developed.
The model structure and underlying equations stay out of view. Users can benefit from your simulation while the modelling methods and know-how behind it remain with you.
Users interact with the inputs and results made available in the simulation interface. They can investigate how the process responds without opening the model-development environment.
Give students a simulation for practical exercises, colleagues a shared process model, and clients a way to explore the model you have developed for them.
Properties behind the process
