• Regarding point 3 ¿did you Extract (Unzip) the ccx folder or just copy paste? You need to unzip. In my case it looks like this: Check those files "cannot stat" thye are where they should

• I have to right click on Loads & Constraints in the tree and then I get the option to set it. Right. It works that way. Take note of the nodes number first.

• ¿Are you considering steel as the main material for the truss?. You have a Young Modulus of 200Mpa. ¿Don't you mean 200 GPa.?

• I have never use it, but you can mesh just the edge nodes with gmsh. Also you could mesh everything and select only what you need later.

  in Where did the solid geometry go? Comment by disla November 2022
• Hi NoahKatz, I would say that both , adding beams to an edge and meshing only one face could be solved once the mesh is generated by adding them manually or removing the unnecessary faces, respectively. If you have a typical step file you normally …

  in Where did the solid geometry go? Comment by disla November 2022
• Yep, -Select all the holes inside surface with the edge detecting tool. -Extrude to the inside direction (normal) to create the solid pipe. Recommended three elements per thickness -Inmediately create a new component. -Hide all but the new componen…

• Hi Dculp, Prop_design Here there is an example with a beam in Dynamic 2D. Dynamic also needs a gravity load to convert the mass into an inertial load. I have found something that doesn’t seem to work but this is not my area and maybe I have set up …
