Hi Elmer!
I have a question: is there means of adaptive remeshing in transition area according to given levelset bandwidth, where levelset function changes the sign?

Hi! Did you look at ElmerModels manual and 4 test cases of level-set solvers? All the information there. https://github.com/ElmerCSC/elmerfem/tree/devel/fem/tests/levelset1 https://github.com/ElmerCSC/elmerfem/tree/devel/fem/tests/levelset2 https://github.com/ElmerCSC/elmerfem/tree/devel/fem/tests/l...

Greetings Elmer users! During my work with Elmer I found that in some cases it is convenient to work directly with SIF files instead of using ElmerGUI. But utilizing Notepad or default editor in the case where we have coupled solvers, a lot of bodies, BCs, BFs etc. is quite heavy. I really like Note...

Thanks for fast ansver!

Hi! During silumin casting solidification simulation I found one unpleasant thing. In boundary layer temperature falls lower than initial condition. I understand that it happen due to high temperature gradient. But how to fix it? Is it mash densifying at boundary layer or smth else? At the 50th step...

And it means I have to learn more about N - S

Anil! Thank you very much for information on pressure BC! It is realy helpful!

Hi Hamed! Thetr was no second velosity component given for inlet. See code below Header Mesh DB "." "TubeMesh" End Constants End Simulation Coordinate System = Axi Symmetric Simulation Type = Steady State Steady State Max Iterations = 50 Steady State Min Iterations = 2 Output Int...

Jay! Thank you very much!

Maybe I mistake but in Boundary Condition 1 Target Boundaries(1) = 1 Name = "walls" Wall Law = True Normal-Tangential Velocity = True Velocity 1 = 0 Boundary Layer Thickness = 0.01 End only one velocity component is zero (Velocity 1 = 0), that means there is flow through wall in y direction.
