Im running a CFD simulation. Looking at improve my CFD simulation. my mesh is currently low density.
Q) Would increasing mesh density around the boundaries of the air craft wing capture the forces (velcoty & pressure) on my velocity map and added streamlines.
Just check i understood this right.
Fig.1 (residual graph) it solving various residuals, residuals being various properity of the object under study (pressure on the wing, velocity of the wing). It is done in iteractions. each iteraction it gets closer to zero, with zero being exact solution...
Hi
Im confused with what the CFD Results show or mean. I have never done CFD before and don’t have any material explaining it.
Question
Find areas of potential inaccurate predictions in the simulation and improvments.
This is the instructions I had to follow...
Looking at past examples of failure in truss bridges, high has been recorded at ends of bridges where failure happened in chord of truss.
With out info of loading or anything. I just don't know on the diagram.
pretty much checking.
Im doing online, so on my own working through this.
only given pic and with the question is do you think that they will be an accurate representation of what will happen in practice?
no data or notes, or info to read on it.
looking through a source i saw that ti said...
I was trying to work out the FEA diagram is accurate, only have diagram. wheather the stress are in right places, wheather this is normal for truss bridge. red max stress, blue lowest.
Hi
im trying to understand truss bridges.
Where would max stress be in single span truss bridge if it was evenly loaded across the bridge?
I thought single span truss bridge, max stress would be in the ends of the bridge. it would act like a simple supported beam with max bending motion being...
Hi
Im slightly stuck not sure what i put is ok.
FEA was used to carry out analysis on 3 structures and diagram results obtain (no data)
Explain where the first point of failure is likely to originate, and why.
An analysis of the studies, do you think that they will be an accurate...
That's what I thought about the diagram and notes being wrong. But unicourse only gave me the diagrams with those notes and won't respond to my emails about it being potential wrong so kind of stuck
Hey
Im doing FEA and got stuck on question. The diagram go me stuck, because looking through the workbook it says high stresses are in red and low in blue, whereas they included both different kind of stresses on the same diagram and no data.
Note: High Compressive strains are noted by blue...
