Re: restart with init file
Hi, The code for producing old.result file Output File = "old.result" Binary Output = Logical True assumes that the directory of the mesh is in the same directory as the sif file i.e. Mesh DB "." "Mesh1" . How do we modify the path for the output restart file old.result...

Re: run ElmerFEM in Google Colab
I tried running this ipynb file with jupyter notebook in my local PC (with all requirements pre-installed beforehand), and it works perfect.
In order to run in the notebook within the local computer, I made the following type of change:

Re: Natural Convection
For obtaining converged simulations with Navier-Stokes equations, it is generally recommended to start the test cases with the following settings:
1. large value of dynamic viscosity
2. very small time step size (e.g. if coordinate scaling = 1.0E-03 , time step can be 1.0E-4 or less)

Re: Hexahedral mesh - error message - magnetodynamic model
Dear Frederic,
Can you upload the file corresponding to the corrected mesh?
Best Regards,

Re: Anisotropic material with StatCurrentSolver
Hi m_nadimii, Yes the electric conductivity materials properties can be a tensor (please refer the following snippet at https://github.com/ElmerCSC/elmerfem/blob/devel/fem/src/modules/StatCurrentSolve.F90 ) . So, anisotropy can be directly supplied via sif. IF( .NOT. GetCondAtIp ) THEN k = ListGetIn...

Re: Crystal_Growth with Phase Change
Dear Roland, The use of mesh update solver is the limiting factor in my guess. It might be useful for shape change or mesh deformation , that happens at a small rate. I do not know whether the eulerian method such as "Level-set solver" is well suited for your case. There used to be an issu...

Re: Issue with temperature dependent emissivity
Dear Arved,
If you can upload a complete sif file with a simplified geometry/mesh file, then we can test it in our computers and provide the feedback.
Best Regards,
Anil

Re: System diverged over tolerance
Dear Peter,
The problem got solved by reducing the timestep sizes further.
In my numerical formulation, the problem disappears when timestep sizes is kept below 1.0E-05

Code: Select all
Timestep Sizes (1) =1.0e-5 ! keeping it equal to or less than 1.0E-05
