Seeking Help for Realistic Masonry Wall Simulation in Flexhopper

Hello to the community,

I hope this message finds you well. I am currently working on a project to create a realistic masonry wall simulation. In my exploration of simulation tools, I initially experimented with the PhysX plug-in. However, I am now turning to Flexhopper as it appears to be more fitting for my final project.

I’ve encountered a specific challenge: the bricks seem to be constrained by an unexpected force in the X direction, adversely affecting the realism of the simulation.

I am reaching out to the community to seek assistance for resolving this issue. If you have experience with Flexhopper your insights could help me a lot.
