I am currently working on a project using ANSYS WB 14 which I am still learning how to fully utilize. I created a frame system using line body elements and want to simulate the effects of a seismic event. Using the results from the seismic event I want to create a tuned mass damper system to...
When I modeled the monorail crane beam I created three nodes: two for the bc's of the beam and the third for where I would add the "pendulum". The beams and the crane cable were modeled as line bodies. I went ahead and deleted the bonded contact and created the joint at the third node. I...
I am building a model of a structure that houses a monorail crane. I built the structure as a line model and want to model the loading of the crane as a pendulum. I added a node for the crane location on the monorail beam, added a line segment to represent the height of the load on the crane...
Well I had a big "aha" moment and realized that I made line bodies from column to column. I changed it to seperate line bodies between the joists and the system now works! Thank you for your patience and help. I greatly appreciate it!
I did end up selecting all bodies and created a single part in DesignModeler. When I go into the Model and try to apply a bonded contact it tells me that the scoping is set to manual and doesn't seem to work. Can you run me through how to apply the bonded contacts? Also, do I have to do...
See attached. The four columns are HSS5x5x3/16, cross bracing are L5x5x5/16, and the beam with the 16000 lb applied load is S15x50. The rest are either W10x12, W12x16, or W12x26. All were added frozen and all bodies coincide with each other...
That is exactly what I did for this project. I also tried creating the same system but instead added all of my lines as "add material" making a system entirely of one cross-section. Performing an analysis like this did not create any issues. With that system of one cross-section I did not...
If you select "add material" is there a way to change the cross-sections of the different members? From what I have seen it appears that it only allows you to choose 1 cross-section by doing that.
On a different note, if I were to model the same system with all members being the same cross-section and when creating lines from points utilizing "add material", I do not run into the issues I am seeing above. I created all lines as frozen so that I can change the cross-sections (i.e. I-beam...
So I dropped it onto model and then had it solve. I have 6 modes of with frequencies of 0, 0, 0, 3.7479e-005, 5.0426e-005, and 5.0426e-005, respectively. Does this mean the system is not setup to act like a rigid body?
So I went back and verified all the material is "structural steel". I then duplicated my static structural analysis and dragged/dropped modal onto solution. I then opened the model and proceeded to solve. I got the same warning as above and a new one:
"You have performed a pre-stress modal...
I have recently been learning how to use ANSYS Workbench 14. I have been working through the examples outlined in "Finite Element Simulations with ANSYS Workbench 14" by Huei-Huang Lee. I am now working on a 3D building frame that utilizes different cross sections. In DesignModeler I added...
I am designing a test setup for a flange-mounted mist eliminator system. The mist eliminator housing is 11.5" ID on the inlet and necks down to a 2.9" ID outlet within a foot. A mist eliminating pad (vane style) is situated within this housing. Estimated flow rates for this system range from...
