Hi,

thank you. Using the UDF worked.

Ah okay i understand. Thanks.

And what if the coordinates represent existing nodes? Is there way to use the node id's?

Hi, does it also works with 4 column tables? For example the first 3 columns contain x y and z coordinates and the 4. the value. I have tried to do it this way Temp = Variable Coordinate 1, Coordinate 2, Coordinate 3 Real include InterfaceTemperature.dat End But unfortunately elmer uses just the 2. ...

Hello, i have a question about the non-eulerian phase change solver (Front Tracking Method). The test case "PhaseChange3" shows an example how to use this solver. The interface is given by the PhaseSurface variable. This variable is the input for the Mesh Update keyword in the boundary sec...

I think i figured it out by myself. In IsosurfaceSolver you can define the name of the mesh with the keyword "Mesh Name". Then you can get the mesh nodes by: Pmesh => Model % Meshes DO WHILE(ASSOCIATED(Pmesh)) IF ( Pmesh % Name == "the name of the mesh") THEN Isosurf=>Pmesh EXIT ...

Ah okay i understand! I will try. Thank you.

Hello Elmer Community, i was wondering if theres a way to use the mesh coordinates of an isosurface or isoline, which has been calculated by IsosurfaceSolver, in a user defined solver. I tried to copy some code from the saveline subroutine, but it didn't work... What i basically need is just an arra...

Thank you for your answer! Your idea sounds really good. But i still have some questions. 1) How can i apply the Reynolds equation for a boundary? In my previous models i applied equations to bodies inside the body section. 2) What do you mean with "reduced dimensional model for the phase chang...

After some hard time trying to calculate the melting velocity, i'm back with another approach for my problem. I read some papers about Stokes's problem with melting, which is also called contact melting. Through all papers they used the quasi-steady state approach, because after some initial time, t...

Okay. Thank you.
