(Structured mesh volume filling, Structured_FSI, Structured multi-material group) etc. I am sucessfully able to replicate this example and also include ambient elements of AETYPE =4 to simulate an infinite fluid region.<\/p>\n<p>But I do not understand the nature of Fluid structure interaction and the behaviour of the lagrangian part.&nbsp;<\/p>\n<p>The example has the lagrangian container defined with a shell element of thickness 0.2 m and steel as the material. But the deformations observed from the simuations are very unrealistic. I have also attempted changing the material properties and shell element thickness, but they seem to show no difference in the results.<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2024\/05\/22-05-2024-1716369629-mceclip0.png\"><\/p>\n<p>Similarly i have also tried to change the structure to a rigid by chaning the material keyword.
