Dear GidList

I am having difficulties with the structured concentration option of Gid 7.2

I have attached a *tif to illustrate the problem. The *tif plot shows the mesh for a 4 sided structured surface where I have attempted to apply the structured concentration option to the vertical sides. It is clear that on the sides (lines) themselves the structured concentration option is working fine. However within the body of the surface I get a rather inexplicable shape. I can get a variety of odd shapes e.g. if I swap negative start weights for positive end weights, or if I flip the normals of the vertical lines to the different senses.

I should point out the structured concentration option does seem to work sometimes. I can't think what I could be doing wrong here? I hope someone can shed some light on this. If this has already been covered apologies.

Many thanks in advance

Send us this geometry file (*.geo) to make some test.
Try also to download the last GiD7.4.6b beta versions (the password remain the same)
