[deal.II] Learning Finite Element Method

I have recently started working in the field of solid mechanics, particularly in the Material Point Method. But for understanding the MPM method, it is recommended that I have a good understanding of the finite element method. Some of the books I referred to are very much detailed and since I a

Re: [deal.II] Re: using .vtk file as initial condition

Dear Anup, Probably the simplest way to find examples of the save and load functionality is to look through deal.II's unit tests . Here are a list of tests that are related to the save functionality $ grep --include=\*.{h,cpp,cc} -rnw '.' -e

Re: [deal.II] Re: using .vtk file as initial condition

Hello all, I shall be thankful if someone could tell me in details how to use 'save()' and 'load()' functions to save and load triangulation information and the nodal values of displacements, strains, stresses, and may be temperature (similar to step44) so that they can be used as initial data

Hi all, I am attaching the sequential and parallel codes as well as parameters.prm file. It would be appreciated if you could compare tangent_matrix (the system_matrix of the elasticity part of the problem) of parallel and sequential codes to find out where I have ruined the S.P.D condition th

Re: [deal.II] maximum value of solution

Hi You are finding maximum at the quadrature points of QGauss(2). When solution is saved, it is evaluated at uniformly distributed points by build_patches. So the two values may differ. To get same values as in your visualization, you can use a QTrapez and QIterated. This combination is explain
