Try Nabla Core and Machines for free for 30 days
Full Machines module, one seat, no card required. While our licence server is being brought online, licences are issued by hand: you send us a request file that Nabla writes for you, and we send the licence back, normally the same working day. One trial per customer.
Once it arrives, import it - about a minute, and the licence is verified offline from then on.
See the full feature/tier matrix for exactly what each edition includes, and the validation dossier for how the solver is checked against closed-form solutions and published benchmarks. Perpetual licences, multi-seat and site licences, and academic and student licences are supplied directly by us on enquiry and are never sold through the checkout - see how to order.
