ERROR!!_PART2_[COMSOL]

Image
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

ERROR!![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 2 (Contineu COMSOL)

Image
Last week , I have created block to put in the COMSOL file , this will assigned as 3D CAD file .Here is the step that on how to make Boundary condition and wire on COMSOL. Create Boundary conditions on COMSOL 1.Open COMSOL 2.Pick magnetic flux and add frequency domain as a study. 3.Add cylinder in Geometry 1 , named as Boundary conditions 4.Set r=15mm and h=10 mm 5.create block(using autocad file last week)                           Cylinder acts as Boundary condition , and Middle point act as wire. *Block,10mmX7mmX5mm *Crack, 5mmX2mmX3mm

[LEARN] Autodesk Fusion 360

Image
On this week , I learnt how to use Autodesk fusion 360 to create 3D block diagram.The block will have 3 type crack which straight line , zig-zag , 45 degree lines. Straight lines crack on block  I hope next week I able to implement this block into my COMSOL. Thanks
