划分网格和加载

小弟想做一个球面，et为fluid29，将球面划分网格然后在nodes加“速度”载荷。建模如图，amesh后出现错误.但是换用结构单元et，1,63就不会有错误，如图。求指教。。

FLUID29 is a 2d element; SHELL63 is a 3d shell element.

Thanks。But if i want to simulate the acoustic environment ,how about FLUID30? Or I just can't AMESH the element?

Not sure what you try to simulate. If you want to simulate the sound wave generated by sphere, use 3d acoustic elements.
