Re: Circuits and dynamics with full coil

Dear Davide,

Eelis Takala worked out very recently a circuit coupling with the coilSolver. You can see some tests in the GiHub repository: https://github.com/ElmerCSC/elmerfem/tr ... /fem/tests

One of the case study is: circuits_transient_stranded_full_coil

Best,

Frederic

Re: unmet dependencies Elmer from PPA ubuntu 20.04 and 20.10

gfortran was installed via the apt. I agree that it is likely that the Elmer in the PPA was not compiled against the fortran provided by Ubuntu focal package manager.

I have no idea what version of fortran was used.

unmet dependencies Elmer from PPA ubuntu 20.04 and 20.10

Dear all, I have tried to install Elmer on Ubuntu 20.04 and 20.10 both without success due to unmet dependencies. Ubuntu 20.04: libgfortran Ubuntu 20.10: libgfortran and libparmetis4.0.3 I am joining a screenshot of the messages. Best, Frederic Screen Shot 2020-11-17 at 16.10.02.png Screen Shot 2020...

Re: Segment error in MagnetoDynamicsCalcFields after PPA update on October 16 2020

Thanks for the explanation. It works fine after the last update done on October 17th.

Segment error in MagnetoDynamicsCalcFields after PPA update on October 16 2020

Dear Elmer's developers, Today, my linux system automatically updated Elmer. Following the update, my code that was working yesterday now shows a segment fault when resolving the solver: MagnetoDynamicsCalcFields My case study is in the link: https://drive.google.com/file/d/11o3ZxE3tLMm-tTT71pnY1RIW...

Re: Filter/masking: regularization of a time-dependent variable to reuse the new results for the next time step - own so

Dear all, Problem solved, I have applied a simple masking to the temperature field through a new solver. If the temperature is below an expected minimum temperature T_min, then it is locally replaced by the expected minimum temperature T_min. In addition to the simple masking, it could be neat to co...

Filter/masking: regularization of a time-dependent variable to reuse the new results for the next time step - own solver

Dear all, I have an issue with the transient heat solver with a quick change in the temperature across a solid. The solution gives some unrealistic temperature values (negative values for instance). It was already discussed in another post (http://www.elmerfem.org/forum/viewtopic.php?t=4004). I have...

Re: Issue with User-Defined Function - Heat Source depending on Coordinates

I have found my mistake. It was a simple typo in the computation of the distance d, instead of the correct d = SQRT((X-x_d)**2+(Y-y_d)**2+(Z-z_d)**2), the code read d = SQRT((X-x_d)**2+(Y-y_d)**2+(Z-y_d)**2) a typo in the last square!

It works now.

Thanks for replying, best,

Frederic

Issue with User-Defined Function - Heat Source depending on Coordinates

Dear all, I am trying to define a local heat dissipation through a Heat Source which depends on space location and time. Thus far, I am working only on the spatial distribution of the heat source in a racetrack coil. The heat is dissipated in a sphere of radius R so that R is larger than the distanc...
