Re: Level set Reinitialization

Dear Andrea,
The test example (https://github.com/ElmerCSC/elmerfem/tr ... allingDrop) illustrates the concepts and techniques for using level set method in Elmer software.

Re: Nonlinear solver computes deformation based on force loads

Hi, The load with the variable name " Displacement i load ", i = 1,2,3 is the nodal force on a mesh. Basically, a target coordinate has to be specified in the mesh for providing the location of action of nodal force. Some discussions on this force are provided in: 1. http://www.elmerfem.or...

Re: CAD/GUI support for Elmer

Hi Arved, Compilation of user defined functions or solvers is very important for adding new mathematical functionalities to the existing modules of Elmer. I have recently tested a python function for compiling ModelPDE.F90 solver to ModelPDE.so . The files have to be kept in the same location of exa...

Re: Non-linear material

Hi, For computers with windows 10, it is convenient to use Elmer software in WSL (Windows Subsystem for Linux). Reference: https://docs.microsoft.com/en-us/windows/wsl/install-win10 Then with Elmer software installed within WSL (installation commands similar to as done in case of Ubuntu) the file (m...

Re: CAD/GUI support for Elmer

Hi Arved,
Nice to know about pyelmer.
I have installed it in my computer.

I will learn some of the tutorials uploaded in the github repository of pyelmer. I will let you know about my feedbacks then.


Yours Sincerely,
Anil Kunwar

Re: How to implement traction boundary condition at fluid-fluid boundary?

Hi, 1. Velocities and pressures are continuous variable over a computational domain. So, one navier stokes solver must work for two fluids (identified by two material properties blocks). 2. For fluids that change shapes, the interface can be tracked by solvers such as level-set solver (present in El...
