I am analyzing a structure with a given set of external loads on nodes. And those loads are assigned to pz as follows.
- Is Pz is positive in gravity direction or vice versa
- When the self weight is being updated during solving for vertical equilibrium, does it replace Pz or get added on top of Pz. If so, to neglect the self weight I can set the density to a negligibly small value, correct?
scale = vertical(form, zmax, kmax=100, density=0.00001)
