"Hello again, I believe the above is an issue with version 1.2.1. I downloaded the latest version from the website (1.2.2) and the reaction forces are fine. Best, Pedro"

Unbalanced Reaction Forces

Hello,I seem to be having some issues with the balance between the applied loads and reaction forces on my model, which do not match (file attached).I was able to locate the issue, it happens when I dis-activate the bending stiffness of the beams ("ModifyElem" component, "Bending" parameter set to "False").The loads and reaction forces are balanced if I consider bending stiffness, but I'm trying to simulate cable elements. Changing the elements pretension is also interfering with the global…See More

"Hi Pedro, you can use truss elements. In order to make them work one has to use second order theory analysis (Th.II) which takes into account the stabilizing effect of tensile forces (see attached definition). Th.II analysis is based on the…"

Cable Net Structural Analysis

Hi Everyone,I'm doing some exercises to explore irregular cable nets and I'm having some difficulty with the structural analysis of them.I think I'm setting up the model alright, but when I try to release the moment joints between the elements (since they are cables, I was thinking I could analyse them as truss elements so I'd have only normal stresses and use the TenComEliminator Component to get rid of compressed elements) I get a "Singular Stiffness Matrix" and the model can't be calculated…See More

"Any ideas? I've tried to unistall GH and reinstall it but didn't work either."

"Hi David,   I'm also having trouble with Galapagos. It works well in another machine that I've already installed GH, but I'm getting a loading error this time similar to the one Jude had. I've tried all the steps above, but…"
