Hello:
I am looking to solve a set of 1D PDEs. I thought the finite difference method would be a good way to go about it. So I decided to pick a simple first order forward difference scheme to obtain preliminary results.
I just have 1 question: According to my scheme, at the last node...
Hi all:
The solution to my problem requires solving 16 PDE's at once. This shouldn't be hard - but you'll know what my problem is in a minute. The 16 PDE's :
∂/∂t (I+i) + Kn*μi ∂/∂x (I+i) + I+i = I0
∂/∂t (I-i) + Kn*μi ∂/∂x (I-i) + I-i = I0
for i's ranging from 1 to 8.
That comes...
Homework Statement
The equation is ut + uux + uxxx = 0
I need to show that this is a parabolic pde.
Homework Equations
Hint : convert to an equivalent system of 1st order equations by introducing an auxiliary variable p = ux, etc.
The Attempt at a Solution
So i took p = ux
doesn't that...
Hello PF users:
I am looking to perform a fatigue and fracture analysis of a machine component subjected to a 2D vibration forcing function. I was hoping that it could be done on ANSYS 12 because I have license to use it but looks like the pre-processing could get very complicated. (I have no...
@Andreas - Thanks for your reply.
I've been spending quite a bit of time on the tutorials, I'm afraid they're not of much help. I took your advice though and tried to assemble the parts separately but I'm not able to constrain the members completely. By the looks of it, the assembly is fine but...
Greetings Engineers
I am relatively new to pro/e modelling. Most of the solids I have created till date using pro/e have been simple ones using mostly the extrude or revolve tool.
I am presented with a problem as I try to create a more complex model of a crane arm ( similar to the arm in -...
