Are you using Windows 7? Try turning off 'Aero' windows settings as it often messes up generated plots. I haven't seen this exact issue before, though. Hope that helps, -Ian "All models are wrong, but some are usefull" - George E. P. Box

I still have no been able to solve this problem. Does anyone have experience with the APDL command 'HFARRAY'? Thanks again... -Ian "All models are wrong, but some are usefull" - George E. P. Box

When I started on FEA (ANSYS user here) I liked to replicate problems from my mechanics text books within ANSYS to see if I could generate similar results as to the book's solution. Always a good starting point. The more you use a particular software package, the more comfortable you get with...

User Base, I'm using Ansys V13 Mechanical Workbench. I am attempting to model a cell of a brazed heat exchanger core with multiple layers of fins/tubes for a homogenization analysis. I want to apply a periodic boundary condition on each plane of the 'unit cell' to simulate the periodic nature...

"Heat flux or thermal flux is the rate of heat energy transfer through a given surface." where is heat flux. As the temperature profile of your part increases, more energy dissipates from the part (Eout increases), decreasing heat flux. Apologies if I am misunderstanding your question...

First of all note that there is an ABAQUS specific forum within the 'Engineering Computer Programs' subset. I can't speak to ABAQUS but in ANSYS you would achieve this with a coupling constraint. A quick google for 'Abaqus Coupling Constraint' provided what appears to be some valuable...

"of course you can buy the CFD Viewer to share your structural results" This is good to know. Thank you. -Ian "All models are wrong, but some are usefull" - George E. P. Box

To my knowledge there is no ANSYS provided workbench 'viewer' program for structural analyses. Linked is the ANSYS product page: http://www.ansys.com/Products/All+Products . Note that there is a 3-D CFD Viewer provided by ANSYS. See this thread for some ideas...

Workbench V14 added a ton of new capabilities that blurs the line between APDL and Workbench. Within Workbench V14 you have the option to view and select nodes, apply nodal forces, created named nodal selections and more. Previously these nodal interactions were only available within APDL...

Maui - Hilarious! #18 had me spitting coffee! "All models are wrong, but some are usefull" - George E. P. Box

Unless you have ANSYS V14, there is no nodal interaction within the Workbench Environment. There are many options within Workbench for mesh refinement: Element Sizing, Method Specification, Mapped Meshing, Sphere of Influence, Virtual Topography, the list goes on. You can select a face to...

I believe you need to edit the 'Analysis Settings' of your Model to include the correct number of time-steps as in your acceleration table. Hope that helps, -Ian "All models are wrong, but some are usefull" - George E. P. Box

First of all please note that there is a separate forum for the ANSYS product family within the 'Engineering Computer Programs' sub-group. Second of all please reference the ANSYS workbench simulation guide (http://www1.ansys.com/customer/content/documentation/120/wb_sim.pdf) . Here you will...

I realize this sounds like something out of an Isaac Asimov story, but what if we had an entire planet of acceptable land for biofuel production? Say, Mars? http://science.nasa.gov/science-news/science-at-nasa/2004/25feb_greenhouses/...

I seem to remember (albeit vaguely) that rotational velocity in ansys (CMOMEGA in apdl) equates the stress and deflection fields from the velocity vectors created but does not simulate the movement in the environment. I'd definitely try using a moment load, although it really depends on your...

Look into the 'Adjust to Touch' contact setting. Also, a quick 'google' for 'Transient Gear Analysis' resulted several links that could be of some use to you...

Sebastion, I'm sorry I wasn't able to provide any better help. I had actually considered modelling a mock up of your problem here at work, but I've been much to busy and we only have one WB license (and 4 people that want to use it!) Here are some of my last ditch thoughts: - Do you have the...

At Northeasern we have an extensive co-op program (regular co-op semesters are 6 months full time, students normally do 3) and companies often keep students on for part time after their co-op semester ends. I know from experience. So the jobs are out there but let me say a couple things about...

Catman: Coming from a recent grad, I think your best bet is to try and use any networking / connections that you gain in school and even in life. Sexual charges notwithstanding, with a low G.P.A. your best bet is to try and stand out through having a good relationship with someone already...

"I have to model it with shell elements. " Okay. "I want to define the connection between the beam and column as a moment frame with semi rigid connection. " You could try using a non-linear rotational spring with defined resistance to achieve this 'semi rigid' connection. My other thought is...
