"Jonathan will share his experience of learning to use MIKE software for coastal projects over the last 18 months. Previous to joining ABPmer, Jonathan was an oil spill modeller and used specialised spill models such as SINTEF’s OSCAR model, RPS ASA’s OILMAP model and BMT’s OSIS model. Jonathan has found learning to use MIKE a steep but rewarding learning curve. Jonathan will take about some of the differences between these models and MIKE, and the lessons he has learnt along the way." Presented at the DHI UK Symposium 2018.

- 18. 17 Modellers Skill 1.2 Assumed User Background Although MIKE 21 SW has been designed carefully with emphasis on a logical and user-friendly interface, and although the User Guide contains modelling procedures and a large amount of reference material, common sense is always needed in any practical application. In this case, “common sense” means a background in wave mechanics which is sufficient for you to be able to check whether the results from MIKE 21 SW are reasonable or not. This User Guide is not intended as a substitute for - and it cannot replace - a basic knowledge of the area in which you are working: mathematical modelling of wave problems.
