Elmer Discussion Forum

well... i add a problem in one of my function in the main python file. I fixed it!

i attached the update files... it works under windows 7, python 2.7 and elmer v8.0

I recognize that this work should be more detailled... one day maybe.. when i will be retired (lol).

Good afternoon to all Elmer users I have a question for Elmer team or Elmer Users of Navier-Stokes solver. There are two logical keywords in NS solver: GradP Discretization and Div Discretization... After reading and reading again the manual, i don't understand what is exactly the aim of these logic...

Hi stroop Yes i know, i had a look to it in the afternoon and noticed two errors in your heat source expression. On "(" is badly written and an other one is missing! I also noticed that you imposed your heat source on the opposite side to the refined one. The right z is around -0.01... You...

Hi have a look to the tests at https://github.com/ElmerCSC/elmerfem/tree/devel/fem/tests check all the heat tests. You may find something that suits your case. To me, it looks simply as 3 differents materials in contact so really difficult to run... just split your 1D line into 3 differents bodies a...

Hello bug and happy new year! Well i don't really use this solver of elmer BUT i can give you few advice when you post a query: - detail your simulation : geometry 3D or 2D? all the boundaries with their condition associated ... - explain what kind of simulation you are trying to run - add your geom...

Good evening i tried to use the adaptive timestepping keyword. It seems to work for the 1st time step and after i've got a strange error... i attached my sif file with keywords for "adaptive timestepping". I also attached the error that i got in my xterm after running "ElemrSolver&quo...

Hi folks! I did not find any post about this keyword "Adaptive Error Measure". This one is defined for "Adaptive Timestepping" ... if i understand the ElmerSolver Manual, this keyword is here to define "own convergence criteria" but i did not find any example??? can we ...

thank you Peter... i will update it... as soon as i can ... It takes a long time to do such a work... i wanted to do the same with a previous work i did 3 years ago... but i lacked of time... My idea was identical to what you said... if more users could use Elmer ... it would also help me to "m...

Here is where i am on the HEAT TRANSFER study of steel wire deposition on steel plate with a Gas Metal Arc Welding process (GMAW). Everything is written in this short report.. normally dedicated to my PhD students... i should have read it another time before putting online here. The compressed folde...

hello dear elmer users as said by Peter, you define the radiation effect in the BC of your problem: here it is an example of one of my boundary (heat problem and i add some comments after !): Boundary Condition 3 Target Boundaries(1) = 3 Name = "plate top surface" !Heat Flux = Variable Tim...
