The core competences within DNV Software used to develop the mathematical models are available directly to those who need them. Our dedicated team of mathematical modellers can undertake a wide variety of projects aimed at:
- developing new models
- undertaking experimental research
- providing an independent review of internal methods and tools or implementation of new methods within our commercial applications
The mathematical models form the backbone of our off-the-shelf software and they can also be customised to meet your modelling needs through our expert tools. These expert tools can be applied to a broad range of situations and are intended for users knowledgeable in the theory behind the models. In many cases they give access to model options or results not available through programs such as Phast or Phast Risk.
