Huzaifa, I am just starting out understanding the deal.II library. I was wondering how complex a problem can deal.II solve. Like for example, if I wanted to analyze a wheel hub and find out the maximum stress for a force at its wheel bolts, would I be able to do it with deal.II? I am sorry i

Konrad, Unfortunately, you will need to do the communication yourself. You can only evaluate the solution on cells that locally owned or on ghost cells. Best, Bruno On Monday, May 11, 2020 at 6:26:47 AM UTC-4, Konrad Simon wrote: > > Dear all, > > I am currently working on a semi-Lagrangian me

[deal.II] Evaluating FE-solution on distributed mesh, semi-Lagrangian method

2020-05-11 Thread Konrad Simon
Dear all, I am currently working on a semi-Lagrangian method for an advection-diffusion equation. During runtime I must evaluate the (known) FE-solution at a previous time step but the mesh is distributed. Problem: It can well be that I must evaluate the solution at a point that is in a cell
