Week 7 - Updating my COMSOL version.

-
 
    On this week , I try with different pattern of crack .. But , unfortunately , it still result the same way with the old plate that I place on the circuit.Below I have several design that i have tested.




                                                        Figure 1 : Sample block with no crack.




                                                        Figure 2:Sample rectangle with no crack.


    Figure above shown rectangle and block which I created using Autodesk Fusion 360.This to minimize the computation progress since it's more simple compare with crack.


                                                Figure 3:Error with same on LU factorization


    I figure out , try to change the version of simulation software , which currently i running at comsol 5.1 , which older compare with latest version , Hope next week , I able to update progress with the new version of comsol.

I've been trying to fix these error , maybe need to change value for mesh and variable , i will able update the solver on the next post , thanks. error: Undefined variable. - Variable: material.sigma12 - Geometry: geom1 - Domain: 3 Failed to evaluate variable. - Variable: comp1.mf.sigmaxy - Defined as: material.sigma12 Failed to evaluate variable. - Variable: comp1.mf.Jix - Defined as: ((comp1.mf.Ey*comp1.mf.sigmaxy)+(comp1.mf.sigmaxx*comp1.mf.Ex))+(comp1.mf.Ez*comp1.mf.sigmaxz) Failed to evaluate variable. - Variable: comp1.mf.Jx - Defined as: comp1.mf.Jix+comp1.mf.Jdx Failed to evaluate expression. - Expression: d((comp1.mf.d*(-comp1.mf.Hx*comp1.mf.testcurlAx-comp1.mf.Hy*comp1.mf.testcurlAy-comp1.mf.Hz*comp1.mf.testcurlAz+comp1.mf.Jx*test(comp1.mf.Adepx)+comp1.mf.Jy*test(comp1.mf.Adepy)+comp1.mf.Jz*test(comp1.mf.Adepz)))*(dvol),{test@6})

Week 10-Troubleshoot [No graph display]

       On this week , I try to re-do the simulation by changing materials that may affected result which generate no output.I also try change the size of minimum element size since I assume the minimum value of mesh may be affected of no magnetic flux numb. Figure 1:Plate mesh size changing to 0.1 , default is infinite.                                  Figure 2:Boundary condition mesh size change to 0.2, default is infinite.                                                                     Figure 3:Error found due to limitation geometry sizes.

ERROR!!_PART2_[COMSOL]

So , i have decided to change value of boundary condition mesh minimum element size , plate mesh size , because last week i have error due to element size , so , i change the value from 0.5 element size to , 0.1 and boundary conditions mesh from 0.38 to 0.2 , figure below ... Figure 1 : Plate mesh size Figure 2 : Boundary conditions mesh Figure 3 :Add new material Then after i change the value and add new material , it display new error and before the error begin , i encounter long time to compute the study.. It takes about 12 hours to complete , but at the end , it display the error says .. Figure 4:Failed to find solution , out of memory.. I hope on the next post , i will about my next step to solve this problem , thanks
