I simulate a seawater intrusion .I open the result form postprocess and check the mass of 250mg/l , the log message says: WARWING:*** ERROR in 'iso 3',(5511>5510)buffer too small! if i  change the 250mg/l into 150mg/l or 300mg/l,the warning disapears.
why?
what does the log mean? how can i do?
any advice is welcome.
thanks

Hi all,
when I set coastal head boundary along the coastal zone, we can give different values to different slices.my problem is this : if the layer is very thick, take 1 layer and slice 1, slice 2 for example,at slice 1, I set the head is 10m, and (10+30*0.25)=17.5mfor theslice 2,(of course the thickness of this layer is 30m ),the head on the layer 1 is a constant,is there a way to get a linear distribution along vertical orientation?
appreciate any help
Thanks in advance

When I simulate 2D model,I don’t know what does the “molecular diffusivity” mean? how can I difine the value? Can it possible equal to a value between  6600 x [10-9 m2s-1] and 18600 x [10-9 m2s-1]?
thanks
