OpenSees Gravity Load Issue

[ebruun]

Was testing the OpenSees functionality. So adapted the posted scripting example (written for Abaqus) to OpenSees, and simplified it to just truss members (i.e., removed the shell element).

Having an issue with the gravity loading not showing up correctly in the introduction.tcl file being generated by the script. This is what is showing up.

OpenSees is throwing an error because it's expecting the loads to be given in 6 dof format in this script. If I add three zeroes to each of these entries the error goes away.

Second issue is that the density of the material used for the truss members seems to have no impact on the gravity loads applied to the 5 nodes. The values are always 0, even with "infinite" density applied to the material.
