Re: Thermal-Stress Analysis in Elmer

Dear Faith, kevinarden has already provided the example for thermal stress analysis in elastic solids. For elastic region, you can use the StressSolver and HeatSolver together. Solver 1 Equation = Heat Equation Procedure = "HeatSolve" "HeatSolver" Calculate Loads = True Variable ...

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:

Code: Select all

%%shell
ls
with

Code: Select all

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)

Dear Frederic,
Can you upload the file corresponding to the corrected mesh?

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
