Hello everyone,

Currently I'm simulate (FSI) blast wave subjected to a structure. I'm facing two problems :

Problem 1) The structure did not deform rigidly (its become/looks like flexible). I want this structure deform rigidly after the blast wave hits the structure. (Figure 1 & 2). It is because of the material properties or the settings ? - Transient Structural.


Problem 2) In CFD-POST, the structure should be deform as the wave hits the structure, but nothing happen. Blast wave just hits and disperse but the structure did not deform. Why this error occur? (Figure 3) -FLUENT-

Thank you for your help and I'm really appreciate.
Hope to hear from you guys soon.
