请教汽车喷油嘴流体网格划分

在下用HEXA LOCK给汽车喷油嘴（如下图）划分了网格，但是导入FLUENT是显示下列问题：

> Reading "E:\Graduation Project\Nozzle\Workbench\nozzle_Hexa_block.msh"...

7238166 nodes, binary.

1000000: Unable to allocate storage [573.517MB] for 21477728 faces.

Reading Faces: failed while reading section 13.

Clearing partially read grid.

Error: Read_Grid_Section: Aborted due to critical error.

Error Object: #f

Error: Error reading "E:\Graduation Project\Nozzle\Workbench\nozzle_Hexa_block.msh".

Error Object: #f

Interrupting...

Done.

请教是不是网格数量太大（700多万个网格），电脑配置不够导致的？而划分流体网格又很难保证skewness小于0.9。小弟把模型传上来，希望哪位前辈能帮忙划分一个skewness小于0.9的流体网格。在下挺急，请求画好的网格文件，能发到邮箱 284533167@qq.com或上传在此处
