hello
i am making a mesh file of a geometry(warehouse having leakage point at some distance from bottom) but the mesh quality is poor and therefore it is not working on ansys fluent.
My procedure is as follows:
1. points < lines < surfaces < create parts < blocking < association of vertices only < splitting < deletion of leakage part block < pre mesh parameters < convert to unstructured mesh < mesh file.

After which step i have to associate curves?

But after doing this the mesh quality is very poor and floating point error is coming in ansys fluent.
plz help me
