Guys,
thank you very much for your answers. I will try to use yours advices in my model and let you know whether it works or not.

Thanks, Roman

Hi all,

I am trying to construct numerical model (fem attached) describing seawater intrusion in the coastal area. My model shows some senseless values, especially high negative values.
Mesh is constructed with help of Advancing front type of mesh generator, no obtuse triangles occurs and the mesh respects the Delunay criterion. Total amount of element in one slice is 9428 and model is divided into 10 layers (11 slices). In the model, two boundary conditions (BC) are set: 1st BC and 2nd BC. 1st BC is set in coastal area (0 m) and in north part, which is opposite site to coastal area (15 m), east and west part of the model is described with 2nd BC (0 m/d).
Concerning mass transport boundary, there is only 1st BC set (35000 mg/l) in coastal area. A 0 mg/l initial mass concentration has been assigned.

Any idea would be great.

Thanks,

Roman
