Thanks for pointing this out! Apologies for the confusion — the file I shared earlier was from some of my test runs. In my actual work I have already set up the analysis with Parallel RCM numberer and Mumps system. The issues I described (non-global response, convergence problems, etc.) are ...

Hello everyone,

I am working on a 3D layered shell FE model of a masonry building in STKO. In my model, the vaults have been neglected, and the vault loads were applied as node forces at the impost nodes. Each floor has been modelled as a rigid diaphragm using the equalDOF constraint, with the ...

Hello everyone!
I'm modeling a masonry building using shell elements and rigid diaphragms.
I’ve assigned the total floor masses (including walls) Mx, My, RMz to the master nodes, which are positioned at the center of mass for each floor. I’ve also constrained the master nodes by locking Uz, Rx, and ...
