Frequently asked questions about our license system, our software… If you don’t find the answer to your question, use our contact form.


Can I test the software before acquiring it?

Yes. Evaluation versions are fully functional and limited to 30 days of use (from the installation date). No downloadable version of ProSimPlus is available on the ProSim web site ; so you will need to get in touch with the Sales Department who will organize this for you.

Is it easy to learn and use?

ProSimPlus use is very intuitive. Users who are accustomed to another simulation tool are surprised how easy to learn ProSimPlus is and how fast they can progress with the software.

ProSim also propose a serie of training courses to allow you to achieve more with the software. View the training calendar

Moreover, you are not alone with the software: the Support team is available to answer your questions.

What kind of process can I simulate with ProSimPlus?

ProSimPlus is a steady state simulator, that will represent continuous processes.
It is provided with extensive libraries of unit operations, component properties databases and thermodynamic models and therefore can be used in many different industries such as chemical, pharmaceutical, petrochemical, oil, gas treatment, refining, specialty chemical.
It is also possible to add user defined unit operations and thermodynamic models to deal with specific applications and extend the application field. ProSimPlus can model complex systems (large flowsheet, with numerous recycling or hignly non ideal mixtures).

Do you have any examples of industrial processes created with ProSimPlus?

ProSimPlus is used in many different industries around the world. Here are a few examples of some common industrial processes. Customers have access to the software file in addition to the pdf of the example by connecting to the Support area of the website.

Can I add my own modules in ProSimPlus ?

Flexibility is a major strength of ProSimPlus. The user has several options to use private modules in the software. The choice will mostly depend on the complexity of the module and on your programming competencies.

The “Windows Script” provides a coding environment to create additional calculation operations (calls to external data, unit operations…). The module is coded in VBScript (a simplified version of Visual Basic).

The user can also create more complex modules in the form of external dll’s, in Fortran or other languages (please consult). The UTI module of ProSimPlus allows calls to this dll and integrates it into the process flowsheet just like any other standard module.

Thirdly, ProSimPlus is one of the few simulators that implements the “Unit” interfaces of the CAPE-OPEN standard. Thus, in the flowsheet, compliant unit operations from other parties (HTRI, gProms for example), can be used without any programming. Should you have an in-house module, ProSim can encapsulate it in the required CAPE-OPEN interfaces and make it usable in ProSimPlus.

Last but not least, you can always ask ProSim’s development team to integrate your calculation methods and models in the sofwtare. This type of project can produce an exclusive version of ProSimPlus (that you would be the only one to use) or an enrichment of the standard version of the software. 

When a problem occurs during calculation, how can I see where the problem comes from?

During the calculation, different colors show you if the unit operation that is under calculation has converged or not. At the end of calculation, if the simulation has not converged, the signs remain on the module(s) that failed. A red cross means that the convergence has failed completely, an orange signs means that it has converged but a warning is attached to it. You are invited to immediately open the module configuration window and in the Result tab, you will find the explanation. This explanation is also found in the Simulation Report, generated at the end of each simulation.
