But It is hard to target what the problem is, if there is a problem. Did you also try if it stays the same without DD? Maybe it is related to the setting of thin dam or porous plate?<br /><br />Beste Regards,<br /><br />QinghuaQinghua Ye2016-08-29T15:10:45ZThin dams / porous platesPhil Shepperdhttps://oss.deltares.nl/c/message_boards/find_message?p_l_id=1806765&messageId=9726792016-07-15T11:41:35Z2016-07-15T11:41:35ZHi. I'm incorporating a single, one cell, thin dam (U) into an existing well calibrated DD model (innermost grid). I then look at the difference between the "with" and "without" simulations (current magnitudes). I am finding that while the wake from the thin dam is visible in the difference file, there are other changes in the magnitude across the grid area, unrelated to the thin dam's physical presence (i.e .the issue is numerical, not real). These changes are quite significant. Same happens with Porous Plate. Thoughts please?Phil Shepperd2016-07-15T11:41:35Z
