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.
