Virtual Fluid Mass / Vibration

[redblack]

Hi there,

Nowadays I'm trying to understand usage of "virtual Fluid mass" elements. You may find a sample bulk file attached which is created by me for an example. Actually nastran gives fatal MFLUID line. It looks like I couldn't define the parameters correctly.

I wonder is there any documents abouts this subject or any example. Any help would be really appreciated about this.

Thanks.

is a better forum. I don't know if this is Mechanical Accoustic/ Vibration issue but since you working in NASTRAN then the NASTRAN forum is more appropriate.
