There is an option to write an APDL code for post processing. Perhaps the code could check the directional deformations of each mode and determine modes of interest.

A continuation to this problem. I drew the correct FBD of the system, shown in the link: http://imgur.com/a/AkTci How is this statically indeterminate system solved? My first guess was to split it into beams which are table cases.

Thanks for the answer. In hand calculations I assumed only forces in the ends of the shaft but for it to be fully fixed there should also be a moment in each end. By allowing the computer model's surfaces to rotate around the vertical axis, representing a pinned support, I got the same result.

I made the simple model even simpler using even numbers in order to find out if dimensions can somehow explain the difference. https://dl.dropboxusercontent.com/u/104865119/ansys2.PNG Did also a parametric study in Ansys and found out that as the length R decreases, the relative difference...

Does anyone have an idea what could cause this discrepancy (121 vs 91 N) between hand calc and Ansys?

Using the global coordinate system found in the picture the moment is about the y axis, My = 100Nm. https://dl.dropboxusercontent.com/u/104865119/hand_calc_2.PNG

Hey, I have a simple ANSYS model shown in link: https://dl.dropboxusercontent.com/u/104865119/hand_calc.PNG . Ansys reaction force in z axis is +121 N and -121 N. Can someone clarify how do you get to this result using hand calculations?

Can the deflection curve of the beam in picture be solved by using the following approach: https://dl.dropboxusercontent.com/u/104865119/beam2.PNG 1) EI w''''(x) = q 2) Integrate four times, solve the constants from boundary conditions (deflection and moment zero at the supports) Thanks...

I'm doing a steady-state thermal analysis for a cylinder geometry. Inside the cylinder is a heat source and this heat is going to water channel (modelled with FLUID116 elements) and the air. For air convection I have to define a heat transfer coefficient which is dependent on the flow of air...

The thickness of the pipe doesn't have to be accounted for..

If we have a pipe with dimensions D=0.006m L=0.01m and a mass flow of m' = 0.019 kg/s How can we determine the heat transfer coefficient of the pipe?

Actually the left part has the same temperature as the ambient temperature because of the convection.

Trying to model a thermal contact between two faces. The plan is to get the heat flowing from the right part to the left part with a temperature BC on the right and convection on the left. At the moment the left part stays in the initial temperature so the contact obviously doesn't work. I...

so bonded contact with only temp dof and bushing joint did the job.

Thank you. I solved this by adding command to the contact keyopt, cid,1, 2 so that the contact only has temperature DOF.
