Hi
I would think that there is no problem that the surface tension is in an internal boundary. This doesn't of course mean that there couldn't be some other problems.

Re: A circumferentially extruded modelling
Hi
The periodic BC needs reference to its counterpart. Hence you should set in your case
It also sounds that you're not getting much output. You might increase the "Max Output Level" to ten or so.

Code: Select all
Periodic BC = 20

Re: Heat transfer in Elmer / OpenFOAM
Hi Walter Number is the primary method of identification of boundary element groups. I don't really know what tool to recommend. Personally I would try to put everything into one condition. For example, if you have dependency on time and on angle you can make a 2D table, read it in the first time, a...

Re: mechano-acoustic coupling
Hi
At least hierarchical coupling from acoutic to elastic, or elastic to acoustic should be possible rather easily (when you know what you're doing...). Perhaps we could write a minimalistic example some day. Seems to be a recurring wish.

Re: Wrong (?) results
Hi Karel
Elmer menu structure is fully programmable so you can add the nodal load to the menus even by yourself. Just edit the corresponding .xml file in edf directory and add "varname Load" to boundary condition menu definition.

Re: Heat Flux BC at Interface
Hi
It may be that the point BCs for nodal loads are omitted. After all in 2D and 3D the Neumann condition cannot be 1D. However, you might use "Temperature Load" as well since the integration weight is one for a node element.

Re: question from beginner
Hi
You could try reading the documentation: startin from the Tutorials to get the idea, and the continuing to Models Manual and Solver Manual for more details on the topics you're interested in.

Re: Memory Requirement
Hi The iterative methods use much less memory, particularly in 3D umfpack is a memory hog. So you could try some of the Krylov methods for your problem as well. In fact the memory consumption of direct methods may grow superlinearly with the problem size. Why won't you just run some typical case and...

Re: Save Scalars file
Hi You should give the filename in order to save a file. Otherwise it is just echoed. By default, all values at point are saved so no need to specify the variables. If you do so, use "Pressure Wave 1" instead. The '.' is just used saved for ElmerPost instead of ' ' since it cannot deal wit...

Re: Heat transfer in Elmer / OpenFOAM
Hi Walter The default user defined subroutine interface includes some Elmer structures that might be difficult to address in C. Hence I would think that it would be easier to wrap the C code in piece of Fortran passing only some primitive data types. Perhaps I understood wrong. What I meant that if ...
