Horay!!

Horay!!!

My simulation results finally seem normal. Phew!

Ok, will try to sound as lay man as possible.

You see, after doing the simulation, i need to extract the strain data from the simulation to compare it with my experimental data of the same setup, expect it is the real thing. The reason why i wanna do simulation is so that i can use the simulation to test out the material properties of the 3 types of solder i have experimented with, to see if it can be used to predict the results of the actual experiment. If it indeed can, then its a success! If it can't, well then too bad. Edison tried thousands of materials to be the filament for his lightbulb before succeeding didnt he? haha.

Anyway, i digress. So the simulation was giving me rubbish strain results!!! the strain output from the simulation resembles something like a 1 yr old trying to draw something... anything. just zig zagged lines. rubbbish (although recently, some elephants in thailand has developed the skill of painting with their trunks. and the painting was auctioned at a price of S$60,000, isnt it better to be an elephant these days?) I digress again, so the funny thing is, the stress value is however very nice, very similar to what i expected the shape of the graph to be like. Which doesnt make sense!! Coz,

Stress = Strain X Young's Modulus
and since Young's Modulus is defined to be a constant in my simulation, then the Stress history graph should have the same shape as the strain!!! But it doesnt!!!

But after me and 3 other PhD students brainstormed for a while, we finally found out its because we had to change this setting for the calculation to be at double precision rather then single precision! >_<

Thus, to keep the long long story short, with a click of a button, my life seems so much less bleek out of a sudden.

Hor!!!
Breakthrough!!! Motivated now liao!!!
Work work work!!!!
