 I thank you first of all for your support. I have a question relating a job that i try to run. I made a Fluid-structure model and i wantes to make an Transient modal or direct analysis for my model. Wenn i run the Job i always the same error:  <<<<  *** ERROR # 2759 ***  There is a transient dynamic loadcase and the model has grids  associated with fluid domain. This solution sequence with  fluid domain is not available. However, FOURIER transient  analysis with fluid domain is available instead.>>>>>>  I tried to look after this FOURIER transient analysis in the help data or a tutorial for that case. but i din´t find something that can help me out. Can you please make a simple Fluid-strukture model in a viedeo and run it so that i can see what wrong with my model ist? else you know a tutorial of a Fourier transient analysis of a fluid- Structure model, that can help me you.  I thank you in advance for you support.

    Hi,

     

    From the error I can see that you are trying to simulate a transient problem with fluid domain. This combination is not available.

     

    But you can try with FRA with fluid domain.
