Hi Anil
Thanks for your kind attention.
I attached the .tgz file.
Best regards, Hamed

Hi dmitry
Thanks for your comment. But the inlet velocity is not 1 or anything else prescribed. It's actually a part of solution.
I hope Peter read this post and help me.
Thanks, Hamed

Hi Matthias
Here is the test case.
Thanks for your help, Hamed

Dear Elmer group
Hi
I’m working on a very simple axisymmetric model of tube with Navier-Stokes Solver.
I apply pressure=5000 pa in the inlet and pressure=0 pa in the outlet.
While the case seems really simple, it does not converge. Can you please help me solve this problem?
Thanks, Hamed

Dear Elmer group Hi I'm using the SaveScalars solver. However, I just want to save pressure (only pressure and not velocity or etc. alongside) without any further operation on it. Which operator shall I use? If no operator is used this error appears: "memory allocation error 4". Thanks &am...

Dear Peter
Hi
I used the following inlet velocity which vanishes on the wall:

Velocity 2 = Variable Coordinate 1; Real MATC "0.24*(0.0015-tx)/0.0015"

Now pressure shows smaller variations by fining the mesh, however, it is not still converging.

Dear Elmer Hi I checked a very simple Navier-Stokes problem in the axi-symmetric coordinates. However, the results for pressure were not independent from the mesh size even for extremely dense meshes. The complete test case is attached to this post for four different mesh sizes (I couldn't attach de...

Dear Elmer
Hi
Is it possible to model fluid-structure interaction between a floating solid like a ship with a fluid with free surface like sea water?

Hi Peter
I'm using Windows 7 64 bit as the OS. Can I install vmplayer on it or ubuntu is necessary for using Elmer on vmplayer?
Regards, Hamed

Dear Elmer group Hi I want to install Elmer 64 bit on my my win7x64. I’ve already downloaded the following packages (64bit-mingw/ and Elmer7.0-rev6431-win64.zip) as Peter said. Now I’m really confused as I can’t find any *.exe file in the downloaded packages after extracting. Does anybody know what ...
