[deal.II] Re: applying 3D mesh in step-20

Hi Kyusik, You welcome :-) No, deal.II only supports quads/hexes so you cannot use prisms. However, since meshing an object with a circular cross section with a structured mesh

[deal.II] Re: applying 3D mesh in step-20

First of all, Thank you very much for your answering my Question. Could I have one more question...? Then, Is it okay If I use Prism cell instead of the Hexahedron cell in UCD format?? Can the deal.II treat the Prism cell?? And, Do you also agree with that "SphericalManifold boundary" is not

Re: [deal.II] Question concerning BlockSparsityPattern.copy_from() member function

Hi Dustin, Thanks for your file. This is indeed a bug in deal.II. Our algorithms for copying the sparsity pattern contain a part that scales quadratically in the number of rows in case most of the rows are empty, as is the case with some of your sparsity patterns. This is very bad if there

[deal.II] Re: applying 3D mesh in step-20

Dear Kyusik, If you open your original mesh file in Paraview (version 5.1 detects it as an AVS UCD file) and you clip the mesh to view its section, then I think you'll see the problem. Although the mesh looks fine from the outside, all of the inner vertices of your torus converge on an annulus

[deal.II] Re: Neumann condtitions in the mixed space setting

Eldar, As you already found out, interpolate_boundary_values can only be used with a ComponentMask if the element you are using is primitive. Therefore, the workaround you are using seems to be suitable for the moment. Since BDM1 is div-conforming, project_boundary_values and

[deal.II] applying 3D mesh in step-20

Hi I'm studying step-20 tutorial example, watching Wolfgang's Lectures In step20, I would like to solve that Eq in the 3D mesh that I made by myself(I attached B_coord3D.inp that is UCD format) But, It didn't work out. The error message is like this [ 50%] Built target step-20 make[3]:

Re: [deal.II] Question concerning BlockSparsityPattern.copy_from() member function

Dear all, some additional information. Out of interest I switched back to the last release version of the deal.ii library 8.4.1 and made a run with this version. The problem is still there and even worse. I attached again the two log files for debug and release mode respectively. Best Dustin

[deal.II] Re: variable time step in step44

Dear Anup, You can reduce current time increment by a “time scaling factor” (I am using 10 or 4 as time scaling factor) . However, it is better to define a “minimum time increment size” to stop simulation when the current time increment becomes less than it. In addition, when the current
