Hi! After installing Deal.II into my machine, it has not passed the quick tests. I have checked the quicktests.log, the error message for all four tests are as below, Start 1: step.debug 1/4 Test #1: step.debug ...***Failed 12.15 sec Test step.debug: BUILD

Pete, When I started to try to implement PETSc/MPI I didn't realize the normal solverSG<> was running with all CPUs. As of now I have no need for PETSc/MPI. I did a little more looking and found that on a single processor it was no faster than the non-PETSc/MPI. For the 3D elastic problem I was

Wolfgang, thanks again for your response. When I started to try to implement PETSc/MPI I didn't realize the normal solverSG<> was running with all CPUs. As of now I have no need for PETSc/MPI. I did a little more looking and found that on a single processor it was no faster than the non-PETSc/M

Pete, Bruno, I assumed that the thread with 100% CPU usage was somehow feeding the others in step-8, It's more like for some functions, we split operations onto as many threads as there are CPUs. But then, the next function you call may not be parallelized, and so everything only works on o

Hi Chang, If you use salome to open your iges files, then it should tell you what is what. Best, Luca > On 05 ago 2016, at 09:19, Chang-Pao Chang wrote: > > Hello, > > I am trying to follow step-54 to register shapes in occ and cells in tria > through projector. > > However, in complex s

Hello, I am trying to follow step-54 to register shapes in occ and cells in tria through projector. However, in complex structure, the order and the type of shapes might be hard to identify. For example, in step-54, they use wire[0] and bow_surface, since there are only 1 wire and 1 face invo
