Re: Save Line in just one body
Hi now I made another workaround. In a used solved I define a new variable "flag" by Exported Variable 1 = -dofs 1 flag and use the force to this variable in the region of interest. The flag can be saved in the output of SaveLine and the required data can be extracted by a python script fr...

Re: Save Line in just one body
Hi I want to have the isoline of melting point temperature in a domain of melt and solid. Currently, I am not interested in the phase transition but just in the change of the isoline in time. I like to write out the coordinates of the isoline for each time step thus getting a time series. Because it...

Save Line in just one body
Hi, I like to write out and isoline (2D computation) but only in one of the several bodies in the computational domain. It seems that Save Line is not restricted by equation setting to a domain but obtain and write out the points for the entire domain. How one can realize to restrict the output to a...

Re: ViewFactors
Hi I identified the main problem. It is the crystal/gas surface in a Czochralski growth furnace. Going from 0.5 mm to 0.2 mm grid distance at boundary gives the problem. When using Viewfactor Combine Elements = Logical False Normalization converges. The crystal has the shape of the experiment thus i...

ViewFactors
I got the error in Viewfactor calculation Inconsistent number of parents found 4134 (vs. 4164) I noticed this is a test on nsurf. But it is not completely clear what is checked. The error appears after changing the mesh density in gmsh. With another mesh the error does not appear and everything work...

Re: ViewFactors
Hi we checked that the geometry is not open. We use the trick with no emissivity on the side of the cave. In certain cases the crystal is just 1 mm longer and the View Factor calculation fails. I also have the suspicion that very fine grid might cause the problem. When the grid in the crystal is fin...

ViewFactors
Hi I have a problem with ViewFactor calculations. I got the message: ViewFactors: Number of rowsums below 0.5 is: 2 (out of 1673) Afterwards Normalization failed. This error occurs in a sequence of computations for a growing crystal in Czochralski process. Geometry and meshing remain the same only t...

Re: Compiling Elmer FEM using CMake under Ubuntu 20.04.1 LTS
check if you have installed the developer version of BLAS .
Only then there will be a link from libblas.so to the recent version.
The search function of CMAKE will only find libraries without version extension, i.e. libblas.so.3 would not be found and give an error

Re: Error compiling cnaitr.f
Is solved by setting
-std=legacy as an additional argument to
CMAKE_Fortran_FLAGS_MINSIZEREL
CMAKE_Fortran_FLAGS_RELEASE
CMAKE_Fortran_FLAGS_RELWITHDEV
the errors are now warnings ......
