icem cfd meshing problem
 

hello... ı am trying to simulate flow around buildings and ı have a model building that has a plus shaped cross-section. ı didn't generate mesh in ansys meshing. can anyone help meshing in icem cfd. thanks....

cut the blocking 2 times for each side of the cross-section (at 33 and 66% length) and remove the 5 inner blocks.
Try for yourself and make a suggestion, upload the prj./tin. and blk.file if you need any help.

As Matthias suggested you need to split your block and remove some of the internal blocks. You will probably need a vertical slice in addition to what he suggested right where the building's roof is. If I remember correctly ICEM had a tutorial for a cube inside a sphere. Take a look at that and with Matthias' suggestion you should be good to go.
