Recently I got access to remote HPC cluster Now I want to ask when I installed moose framework from moose website it has many But after getting to HPC cluster I have nothing but empty folder. Can you please tell how to begin with first of all should I download moose framework from github and copy folder to cluster and try practice how it works Any suggestions how to begin with as I'm new to this I have experience in comsol only but recently got project relevant to moose framework. I have limited friends working on it please just suggest how to approach this app. |

Hello If you just want to get started to try the software I would follow the getting started / linux instructions on our website If you want to get a fully performing moose install to do large runs you will want to follow our getting started / HPC install instructions Guillaume |

these are module available on cluster i successfully loaded these on hpc cluster the again i copy all the moose directory on my cluster and again in examples directory when i run make -j 6 command it does not create executible the error is [ms23mtech11003@sukshma ex01_inputfile]$ ls the error is shown here please suggest im unable to properly utilise moose framework |

Thanks sir now I'm successfully able to run it. One question? I'm beginner at it Building physics module from scratch itself! How feasible is idea to propose to my guide ! How to approach moose documentation for that? Thanks |

Hello It is a great idea. i would recommend finding a good name and making sure it is a clear delineation from other modules. the best way to get started with both the code and the documentation is to run the Guillaume |

in the kernels and boundary conditions
we do. You only need to write the term at the quadrature point, we take care of the summation |

@GiudGiud im learning about my problem but first i want to understand documentation of moose framework. where we put these discretized iterative jacobian/residual matrix in which i get that note:- MOOSE handles multiplication by the Jacobian and the weight automatically, can you explain above sentence what exactly upto where kernel is calculating is it just assemblying the jacobians and residual matrix and take them to nonlinearsolver kind of thing if so why we dont put discretized form of integrals(iterative summations) in those kernels src codes |

The kernel is in charge of computing the term for a single quadrature point. |

https://mooseframework.inl.gov/modules/phase_field/Phase_Field_Equations.html please visit this link here you get this kernel ACInterface.c & ACInterface.h
i also attached their src code link can you explain how this code implementing that part of residual this would improve my understanding how coding approached in moose framework |

@GiudGiud can you please just explain the residual and jacobian part of code how moose approach this kernel. |

@GiudGiud sir i understand how to put weak form of differential equation in kernels can you tell me if my weak form contain double summation how to approach that |

hello you can have a double summation inside the kernel computeQpResidual routine. These will just look like two nested for loops in C++ |

your linear solve is failing. Can you try a simple -pc_type lu? |

Please refrain from posting pictures of text. Also, please do keep in mind this thread has gone entirely astray from "Q&A Getting Started", and belongs in a separate subject group entirely. I do not know how this post will have an answer. Do I help you with your original Peacock issue? Or do we answer your equation questions? I stopped trying to answer, because I feel I will derail your other questions! |

I am reading this entire post from the beginning, and you have asked many different unrelated questions. Please use a new discussion for each separate new question.

I'm running Moose in dual boot mode Linux
I have followed all the guidelines for Moose installation and create Moose environment successfully.
But unable to launch peacock gui
I have tried both path
Both contain executable
I tried running command in both their own directory including their executable
Even tried in my app which contains Moose opdt example executable
I tried this while remaining in Moose framework
Earlier tried getting same things done in peacock environment as well
