gPROMS Reviews & Product Details

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.

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.

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.

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.

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.

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.

I used gPPROMS and gCrystal in all my 4 years of PhD and I should say I really enjoyed it since oncevyou learn how to work with it you do not want to go back to other programs Review collected by and hosted on G2.com.

Why isn’t it yet everywhere???

I also miss online help when you have problem it is not clear how to solve it Review collected by and hosted on G2.com.

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.

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.

It allows to customize the existing Unit Operation Models in Equation Oriented approach to easily understand what is happening on the backend. Review collected by and hosted on G2.com.

Its UI/UX are not modern.It needs further development based improvements in future releases. Review collected by and hosted on G2.com.

Very user friendly, includes various modes, steady state and dynamic, flexible to add codes for new correlation as well as built-in units with their built in equations Review collected by and hosted on G2.com.

using another software to create a stream with its details, including compounds, temperature, pressure, composition, etc. Review collected by and hosted on G2.com.

The syntax is quite logical and if you are familiar with coding, it's easy to get the hang of it. It can also plot graphical data. Review collected by and hosted on G2.com.

It is not as widely used compared to languages such as Java and Python so there aren't too many solutions or advice online Review collected by and hosted on G2.com.

I love the way it explains process system engineering and the great tuition it has. the variety of examples you can start with and the kindness of customer services. Review collected by and hosted on G2.com.

It does not have other things other software might offer like more function like error function etc. it can be used if you are Matlab or python user but not the other way around if i remember correctly. The error message can be more specific and there is a chance for improvement. Review collected by and hosted on G2.com.

Provision of formation of complex process models for new applications/non-standard unit operations and it also can be used for batch and continuous processes Review collected by and hosted on G2.com.

Process modeling is very hard as coding requires a high level of accuracy Review collected by and hosted on G2.com.
