Re: Solid-liquid phase change

Hi Martin, As far as i can see in your SIF, the Enthalpy is way too small. I dont know what values you are using, but try with multiplying by 1000 as the unit of enthalpy should be J/m^3 . (333 kJ / kg, density = 1000 kg/m^3 --> 333 MJ/m^3). Your cp is in J/kg K i think? In addition to Peters link, ...

Heat Flux and Paraview

Hi everyone, I have a simple question regarding Elmer and Fluxsolver: I have searched on the net and here in this forum, but i cant find an answer. I have a test case with transient heat transfer 2D. I applied a body force on one body (in the middle) and the two other bodies are heated by that one. ...

Re: Phase change / switch variable

Hi everyone, It took quite a while, but i finally managed to restart my project (again), with some changes: The working UDF: FUNCTION phase(Model, n, temp) RESULT(ent) USE DefUtils IMPLICIT None TYPE(Model_t) :: Model TYPE(Solver_t) :: Solver TYPE(ValueList_t), POINTER :: material TYPE(Variable_t), ...

Re: Phase change / switch variable

Hi Anil, Unfortunately I haven´t managed to get any further. I restarted the whole UDF to some very simple things today. This will take some time to get at least a few results, i could perhaps present. By the way: Is it allowed to use Elmer FEM and results thereof in a paper or Thesis? Of course wit...

Re: Phase change / switch variable

Hi Matthias, Yes, that was what i wanted to do. This far i couldn´t get to the nodal values of temperature due to lack of programming-knowledge of myself :( But i thought, if i get the time and temperature via the "variable ..." in the material parameter, that i already have the nodal valu...

Re: Phase change / switch variable

Hi Anil, Unfortunately I didn´t try the time dependence any further. I Fear it will take some weeks until i can finish this, if at all... Currently i am stuck in getting the time into the UDF (With "variable temperature, time" in SIF). thats fairly easy to do, but it looks like only the ac...

Re: Cannot find shared library

Ok, I have found the Problem.

The compiler is creating an "a.exe" in the directory. I just renamed it to "PCMUDF.dll" and it worked.
But: is it possible to set the "preferences" for the compiler, so it can create the dll only?

Thanks in advance

Re: Cannot find shared library

Hi there, I have the same error with the newest version (7.0 Rev 78cf1f8). I imported a Project (which was running without flaws) of a previous version in the GUI. i also recompiled the UDF using the "compiler.." menu item. Still, no errors. If ihit start it says this: Loading user functio...
