Hi! Mark, the last thing I can do for you is to make simple resolved case. This trick works. I may even to save this dummy property "c_rho" with "SaveMaterials" subroutine. Here the reference to my google drive: https://drive.google.com/open?id=0BycAFyxqap6ELTlYOWN4VUJpYUE Try to...

Hi! I use folloing version: ELMER SOLVER (v 8.0) STARTED AT: 2016/06/10 15:24:24 ParCommInit: Initialize #PEs: 1 MAIN: MAIN: ============================================================= MAIN: ElmerSolver finite element software, Welcome!

In the material section definition for "c_rho" property is not correct: Material 1 Name = "fluid with constant properties" Viscosity = 11.364e-3 Heat Conductivity = 0.174 Heat Capacity = 1632.0 Density = 1194.5 $ c_rho = Cp*rho End "c_rho" should be specified like this:...

Hi, Mark! It's strange. May you supply your sif?

Hi! I'm also model N-S + Heat coupling. As I see, you want to know convective heat flux through boundary. I guess you need to do following: create dummy material property c_pho, that will present multiplication of dencity and heat capacity. If it depends on other vars., you should give dependency as...

Hi! I have looked and repeated your case and I have following results (may be I'm wrong, because my experiense of CFD half a year): Reynolds number of your case is about 10600, that means your flow is turbulent. To simulate Steady State folow you need to apply some turbulence model (k-epsilon, for e...

Hi! Cool tast! I've tried it. So, NS solver fail to converge at 80th timestep when fluid contacts with right wall, isn't it? Here some pictures (the line is interfase): Velosity (80th time step): http://i61.photobucket.com/albums/h49/79536012595/Velosity_zpsjsqj5myf.png Pressure: http://i61.photobuc...

Yes Mzenker is right, sometimes I foget about scale too

Hi!
As I know, unfortunately, there's no gui definition file (.xml file in \Elmer 8.0-Release\share\ElmerGUI\edf directory) for LS solver. The only way to implement GUI for LSM is to write .xml file for it.

Hi! May be I'm wrong, but In the code Boundry Condition 5 seems overdetermined: Boundary Condition 5 Target Boundaries(1) = 5 Name = "BoundaryCondition 1" Heat Flux = 150 External Temperature = 288 End External Temperature do not play any role here. It sould be Heat Flux condition only Bou...
