urgent help needed for meshing in GAMBIT

chris

I'm modelling an artificial rectangular channel whit a groyne (perpendicular wall to side wall). The bottom has a local scour around the groyne. I'm using meshing cooper scheme. I have split the top and the bottom surface in three different surfaces in order to refine mesh better. When i refine the mesh edges and apply the cooper meshing scheme, gambit shows in transcript window: " errorut of memory". Gambit and fluent are installed in IBM SP 9076 and i'm working by telnet. The process of meshing volume is possible whit a small number of mesh element (5-6000) and it is very slow. What is the cause? I'm seeking everyone for helping myself, thanks!
