Day 32

Good afternoon, I was unable to come into school last week because my car was in the shop. However, I reached the end of the homogeneous precipitation stage of the paper, which is great, but, I've got some errors at the very end. These errors are similar to the ones I fixed before using the commands that I am using now. So, I need to figure out how to fix these same errors without using the commands I am using now, because the commands I am using now are what fixed the errors to begin with. Back to square one with error fixing. That's what I will be working on tomorrow and the next day until all errors are fixed! 

Here goes nothing!

Day 31

As you know for the past few days, I've been vehemently trying to fix some errors that MATLAB is giving me. There was no difference today until EUREKA!!! I FIXED MY ERROR...by completely scrapping what I was doing. I searched and searched and found a different way to solve differential equations. So the reason why I didn't not blog a second time yesterday is because I couldn't fix my errors BUT I did fix them today!!! 


Case in point I can now move ahead with the other differential/integration equations! SO HAPPY! Therefore, I will get back to it and I hope everyone has a FANTASTIC weekend!!!

Day 29 & 30

For the past 2 days I've been trying to fix the errors I am receiving when running my code. So far, I haven't fixed them, which is a real drag. I've tried using the inline command, creating a function and using the dsolve command to solve the integration symbolically but nothing has worked yet.


Right now, I am trying to fix the error I receive from using a function. I have deceased the number of errors to just one, which is good, but I do not know how to fix it. Therefore I must search online to see if I can dig something up.


I will return later today....

Day 28

As I stated yesterday I would be looking into the ode solvers that MATLAB employs. I've begun to utilize the ode solver and inline command in my program. I've come up with a few ERROR lines:

??? Error using ==> inline.feval at 26

Too many inputs to inline function.

Error in ==> odearguments at 110

f0 = feval(ode,t0,y0,args{:});   % ODE15I sets args{1} to yp0.

Error in ==> ode15s at 228

[neq, tspan, ntspan, next, t0, tfinal, tdir, y0, f0, odeArgs, odeFcn, ...

I've been spending my time looking up how to fix these errors and testing the solutions out on my own code. I receive similar errors; therefore, more digging on how to fix these errors is necessary. Also I will ask Prof. Graham for a little help too.

Day 26 and 27

I'm back from my birthday celebration/vacation and back to business. I met with Prof. Graham.  I told him I am solving the equations using the symbolic solver. He stated there is an easier way. For the nucleation and growth section under homogeneous precipitation I can use the cumsum command, which I implemented. So that is one section changed. 


Next for the growth and coarsening part under homogeneous precipitation he stated I use the ode solver, which I have never used before. I'm using The Intro to MATLAB for Engineers to help me with the ode solver. I've started to input that into the code and so far so good. I'm not sure if I need to separate variables to use the ode, but Prof.Graham stated that I need to; therefore, I am trying to separate the variables of the equations first. I'm having a bit of difficulty, but I'm sure that's from not using my brain for the past 2 months.


Lastly, I am getting the computer I use in the lab updated, so new windows, MATLAB (which is essential), FEMAP etc. I'm really excited because everyone in the lab either got new computers or got it updated and mine never got updated. I decided to get it done before school starts, which I think is a good idea. Especially if other students may need it. 


Anyway, I will be returning tomorrow morning to continue this work.
