Anaqsim – The fastest and most flexible groundwater dewatering simulator

Update your construction dewatering simulations in minutes, not days…

Built for everchanging plans, geology data and deadlines​

As the project engineer or geoscientists you recognize that dewatering projects are rarely straightforward

Designs change frequently
sometimes overnight—forcing you to adjust excavation depths or configurations

Site conditions are anything but predictable;
new geological data is constantly emerging, adding complexity to your already tight schedule.

Data arrives in pieces
sometimes too late—and is often spatially and temporally limited, leaving you to make critical decisions with little time to spare.

​Whether it’s modifying geological boundaries, updating hydrogeological properties, or refining your dewatering strategy, Anaqsim lets you make these changes very quickly.

​Need to iterate your design with new data? No problem. You can prototype multiple scenarios and test the sensitivity of your assumptions with just a few clicks, ensuring you stay agile even when data is limited.​

The analytic element method (AEM) is attractive for small-scale local problems like the design of a temporary dewatering system because of its flexibility and simplicity.
