looping elmer solver with different boundary condition

[siti.nurhasanah]

Hi, i attach my sif file
i hope somebody can check this and find what is wrong with my simulation
when i running the simulation sometimes it can finish running, but sometimes it show error message:

ERROR:: IterSolve: Failed convergence tolerances.
ERROR:: ComputeChange: Norm of solution appears to be NaN

Thanks before

Hi,

I think your tables are ill defined. You have multiple values for the potential assigned to zero time. I would fix this first. You also have defined timesteps of size 0.5 in the Simulation section, whereas in a scanning simulation the size is 1 (see Peter's post earlier in this thread). Maybe Elmer will just ignore it, but to be on the safe side, I would set Timestep size to 1.

HTH,

Matthias

thank you for your suggestion,i will try it more. i'm waiting for other suggesstion about my simulation from you
thanks before

Matthias is right, the dependence table [x,y] should be such that x is a monotonically growing series. Otherwise linear interpolation is not possible. -Peter

I would suggest that you fix the tables and see if that solves the problem. If you still get trouble then we can look where they come from.
