Research Assistant Enterprise (\> 1000 emp.) 2/9/2021 "Powerful, but use with caution!" 3.5/5 What do you like best about gPROMS? gPROMS provides unmatched for power and speed, when it comes to modelling and simulation of complex dynamic systems. Part of this strength comes from the implementation of the equation solvers, that are capable of solving even PDEs in a fast and reliable fashion, a feature that even established programming languages such as MATLAB or Python struggle with. Optimization is also uncomplicated and easy-to-implement. The solid object oriented programming style and use of modules makes creating DRY code easier. Review collected by and hosted on G2.com. What do you dislike about gPROMS? The error analysis tool is very unforgiving, as it keeps shouting for the smallest mistakes (e.g. fixing an extra variable in an algebraic equation system can lead to 80 unrelated error messages) which can result in painful headaches. The user interface (GUI) is quite basic and has a lot of room for improvements, especially given the fact that occasionally the coding syntax can be unintuitive. Also the user support system is quite ineffective. The coding style in itself is hard to follow, especially without any official or extensive user manual or educational videos published, which is topped by a small user community. Therefore, when facing a challenge it is almost impossible to get help. Review collected by and hosted on G2.com. What problems is gPROMS solving and how is that benefiting you? The high speed in solving complex systems and optimization problems is second to none. I used it for a course on dynamic systems simulation. Review collected by and hosted on G2.com.

Enterprise (\> 1000 emp.) 1/9/2021 "gPROMS:The best tool for Advanced process modelling" 5/5 What do you like best about gPROMS? The best tool available to model, simulate and optimise complex systems. Its powerful built-in solver are excellent for solving systems featuring ODEs and PDEs. Except from standard flowsheeting package, PSE offers the possibility to create default models and libraries custom made to your needs. Its language resembles the way you would write the equations on paper, making it quite easy to master. Probably the most useful features for an industrial or research organisation are the optimisation tool and the model validation feature. The first one, is a very powerful tool with many benefits, as it allows the user to optimise very complex systems, which is impossible with traditional tools. The model validation and parameter estimation tool of gPROMS is essential for any organisation that wants to create its own custom models for their process/technology. It has the potential to lead to very reliable and accurate models, but also minimise the amount of experimental activities that are required to reach the result, leading to large savings in time and money. Review collected by and hosted on G2.com. What do you dislike about gPROMS? Personally I do not dislike anything particular about the tool. Of course in order to use it, someone has to be proficient (at least at some degree) with process modelling, programming, advanced mathematics etc. Nowadays, university graduates are more an more capable of using computational and given the extensive customer support given by PSE, it will not be difficult for them to master the software, but I can see why engineers of older generations would find it difficult. So the training required would potentially be a downside, but I believe that it is an investment worth taking. Review collected by and hosted on G2.com. Recommendations to others considering gPROMS: I would recommend contacting PSE (the company that developed gPROMS). They provide a plethora of different packages, solutions and support in various levels of your project, so do not hesitate to involve them in your decision making. Review collected by and hosted on G2.com. What problems is gPROMS solving and how is that benefiting you? The main problem I solved with gPROMS was to model, simulate and optimise a separation unit operation. The software was a lot more powerful (especially in the solver initialisation and optimisation) compared to the alternatives (e.g. Matlab, ASPEN etc.). It really heped to reduce the time needed to solve the problem as I had to invest way less time to write the solvers myself. Review collected by and hosted on G2.com.

Chemical Process Engineer Small-Business (50 or fewer emp.) 12/13/2020 "Easy to model" 4/5 What do you like best about gPROMS? To insert information and set variables and and other parameters there is very helpful and easy to do and you will get different results by simply changing the variables in your problem and in that way you can generate as many iterations for your problem as you want to. Review collected by and hosted on G2.com. What do you dislike about gPROMS? Sometimes it becomes troublesome to identify different parameters, assigning nomenclature to parameters and complete the information for getting results. Review collected by and hosted on G2.com. Recommendations to others considering gPROMS: It will help you in your initial modelling of projects and in generarting results for analysis and comparison between different results. Review collected by and hosted on G2.com. What problems is gPROMS solving and how is that benefiting you? If you know how to use this software and knows how to insert information and once you have done all this then it is just one step away to get your results. For getting results without this software is a lengthy process Review collected by and hosted on G2.com.

Scientific project manager Mid-Market (51-1000 emp.) 1/19/2021 "Good flowsheeting environment for modelling of novel processes" 3.5/5 What do you like best about gPROMS? I find gPROMS is a very useful resource for custom modelling (gPROMS ModelBuilder) and data regression (parameter estimation), to implement user-defined models of non-conventional process units into a full flowsheeting environment, . Review collected by and hosted on G2.com. What do you dislike about gPROMS? I think one of the downsides of gPROMS is the proprietary language syntax, which is sometimes less intuitive and compact than C++, for instance. Review collected by and hosted on G2.com. What problems is gPROMS solving and how is that benefiting you? I have used gPROMS during my PhD research as main tool for modeling electromembrane processes (electrodialysis and reverse ED). The benefit of using gPROMS was the possibility to implement a custom model of the main process unit (reverse electrodialysis stack), and then run simulations of the whole process.
