It means it's not changing (much) at the position you're monitoring. I can't tell you a solution is correct without a lot more information (which I'm not allowed to do) and also because I'm not permitted to tell you if a model is correct (I've got to be careful regarding experience & engineering knowledge to adhere to the Export Laws).Â
What I do suggest is doing a lot more post processing and discuss both the model and results with the project supervisor. Explaining what you've done to someone sat with you will highlight any oddities in the results, but you'll also spot things as you explain.Â
