Is it possible to create transient response analysis for fluid domains?

Hello everyone,
i'm trying to do a transient response analysis for a empty room using hypermesh/optistruct. For that i only modelled the fluid part of the room an created Absorber elements at the boundaries with a impedance, that results in a small amount of absorption. A direct frequency response analysis works perfectly, even though the results are not as wished. Trying to change the analysis to a transient one results in the following error:
A fatal error has occurred during computations:
*** INTERNAL PROGRAMMING ERROR # 251 ***
Specified vectors (1 - 1) out of range (1-0).
Thank you all in advance

Hi Dennis,
Transient analysis for fluid is supported.
The attached is an example for your reference.
Thanks.
