Re: SaveScalars: int mean for a volume

hmm, that (int) mean thing would be confusing from what yout said and what's in the manual. I used max and indeed it found a max of 74deg. But I cannot see that in my setup in postprocessing. The highest Temp I have in all of my setup is ~75, but that is far away from the body I run the SaveScalar s...

Re: SaveScalars: int mean for a volume

i'm not quite sure how this helps me. It finds the highest temperature of all the nodes within your body. But it does not compute an average. As solvers area always computed on bodies the int mean should give me the mean of a body. The manual explicitly says so: "There are also a few operators that ...

SaveScalars: int mean for a volume

hi all, I am somewhat confused on how to use the SaveScalars solver. I have the following setup: a tube for which I have a Navier-Stokes and a HeatSolver. The tube has boundary conditions for the input and output side setup. The material within the tube is water. I would like to know the temperature...

Re: Elmer mesh from gmsh

It can read step files, but I haven't tested how well it works when I manipulate it. In general it looks promising, at least for the low complexity geometry I currently work with. I haven't tested if it keeps multiple bobies after changing the imported geometry

units after coordinate scaling

hi all, a basic question about the coordinate scaling capability of Elmer. Let's asume my geometry is constructed in mm, but for all my results and BCs and body forces I want to use SI units, i.e. meters. I use the coordinate scaling = 0.001 option. From that point on everything should be alright? W...

Re: Elmer mesh from gmsh

Well I had a look at Salome for this matter. Although being one of the better tools for preprocessing it is a bit - say clunky. You have to create a partition from the different regions you want to mesh and then also indivudual groups for every volume. In the Mesh module you then mesh the partition ...

Re: Elmer mesh from gmsh

Thank you for your advice. My final goal is to import a more complex structure into Elmer, which are too complex for designing them manually in gmsh or netgen. These parts contain multiple bodies which must be connected to each other when meshing. This is no problem when "code"-constructing them in ...

Elmer mesh from gmsh

Hi all, being new in the FEA field of work I'm struggling getting to work with Elmer. I use gmsh to make a simple geometry, it's just a bigger block with a small block sitting on top. In Elmer I want them to be treated as 2 bodies, as the smaller one shall have a body heat force, and one side of the...

Re: gmsh to Elmer

hi, since I also have a problem getting a gmsh into ElmerGUI which has multiple (2) bodies I wanted to try your Method. I have little experience with FEM, Elmer and Gmsh. Can you please tell me where I can set the format version of the .msh? When I regularly export a mesh with the "File->Save Mesh" ...
