Need help in meshing
 

Hello everybody!
I'm new to both CFD-Online and ANSYS. Recently, I started a project and I'm kinda stuck with it now. The project is about designing an industrial chimney. I did the modelling and now I need to mesh it. Unfortunately, ANSYS12,13 failed to run on my system (Win7 x64). Every time it comes with a license error. I don't know whether its because I'm running 64 bit or not. So, I decided to run Windows XP in vmware and ANSYS 12 did work on it. When I try to mesh the model in ANSYS 12running on this virtual machine, I get a memory limitation error. I don't have a good hardware to run this file. (3GB DDR3 + Core i7 920). Will anybody kind enough to mesh it up for me? I need to submit the project by the end of this week. Thanks in advance.
Here is the download link for the ANSYS v130 db file
