Minimal deformation in the event of 100kg tnt explosion

Hello my name is Enrique,

I have been trying for a long time to successfully couple Blastfoam (a compressible gas solver based on OpenFOAM) with CalculiX to study the deformation of a building in the event of a 100 kg TNT explosion. I have managed to run the coupled simulation successfully without errors, but I don’t understand why the building’s deformation is almost negligible (on the order of 10^-4 m), which is impossible. I also noticed that the velocity UUU is very low, around 2/20 when it should be in the order of hundreds or a few thousand. I am completely lost and I am in a hurry. Any help would be greatly appreciated.

I added all the folder and the precice configuration.

Thank you in advance.
