Hi Ido,

 

Sure. I have a block sink in the water, I first apply gravity on it and then apply earthquake motion to the tank. We want to see what is the response of fluid under earthquake loads. So when the analysis is done, I just pick my block first, go to post setting apply scale factor of 5 to see what is the displacement of the block. We do amplification to make sure there is no torsion in my block. One way to check our model is applying displacement scale factor to see how does the animation look like. We want to do the same thing with the fluid in the tank. I turn on fluid part (ALE water) and want to see  what is the response of water. when the scale factor is 1 everything looks correct. We want to apply amplification factor of 3 to the ALE part to see how is the amplified version of the fluid displacement look like. But when I go to post setting and apply scale factor 3 to displacement, the whole part just jump in horizontal direction and the surface of the water doesn't change. I make a screenshot and send it to you to see how does it look like. the scale factor 1 and scale factor 5 are basically the same. But when I apply displacement scale factor to the structural elements, it will really amplified the displacement 5 times (whatever I want) and I can see real changes. I wanted to see if there is anyway that I amplify displacement or deformed shape of fluid? Please let me know if you need more information,
