Hello,
I have set up my file according to a previous tutorial that worked, and I currently have beam members in just the X-Y plane. I also have a few nodal forces in the Z-direction. With the settings that I have, I can run the simulation, but as soon as I attempt to draw members in the z-direction, I receive errors. I have tried to change the orientation of these beams, but that hasn't changed anything. What can I do to fix this?
Hi nch315,
Did you try looking up the error message in the Help? That would be my only suggestion.
Otherwise, a little more information might help someone to solve your problem, such as
I'm not sure what the 503 error was, but it is probably an indication that the solver encountered some type of error (math error? poorly defined stiffness matrix?). One solution may be to go into the Analysis Parameters ("Setup > Model Setup > Parameters"), go to the solution tab, and change the type of solver. (Since your model is small, you can try the iterative. If that does not work, then change to the sparse. If it was a large model that ran for a long time, I would look at the summary file to see which solver was chosen as the "default" and then manually switch to the other type of solver.)
When you drew the new beam elements extending in the Z direction, did a node on the new beam coincide with a node on the existing structure? One important thing to remember in Sim Mechanical is that internal forces and moments are transmitted from one element to the adjacent elements through the node. So if the nodes are not connected, there will be no load transfer. Typically, nodes are connected because the two elements share the same node number. In the case of surface contact, the software creates an element that connects the two nodes together, and part of the solution is whether the two nodes come into contact (the nodes move closer together) or separate. In some cases (MES and thermal?), these contact elements are not shown to the user. Another, advanced method of connecting nodes together is through Multi-Point Constraints. Most users never use these manually, but the software creates them automatically in some situations ("smart bonding", cyclic symmetry, and ???).
