Re: [deal.II] Re: .msh file triangulation failed
Dear Bruno,
Sorry for the late reply. Here is flooding, I was driving home hours
before. You are right, in the linux version of gmsh, it always gives the
error message that cannot find the corresponding vertex, but actually I do
nothing on the cell. It is the 1e-7 rounding error that makes the system
very unstable. Thank you again for your patience and kindness. Have a good
day!
Best regards,
Yuesu

Re: [deal.II] Re: .msh file triangulation failed
Dear Bruno,
I did some modification according to your suggestion :
*Physical Volume("4") = {1};//+Physical Surface("0") = {4, 3, 2, 5, 1, 6};*
I add all external surfaces in one physical group and the volume in another
group. But the error message remains the same. I tried a few types of
grouping combinations, the error message did not change.
Best regards,

Re: [deal.II] Question about fe_value.divergence
Dear Dr. Bangerth, Thank you very much! I was confused about the shape function in the vector case. In step.8 we use the FEValue::shape_grad(index of shape function,index of quadrature point) and get a vector as the gradient of shape function. However, in step.20 and step.22, when we take the gradient of FESystem[vector_indices]::gradient(index of shape function, index of quadrature point) we get a rank-2 tensor. If the shape function is a vector, FEValue::shape_grad(index of shape function,index of quadrature point) should give a tensor as well. Does it mean that the shape_grad gives the gradient of the non-zero component in the vector shape function such that it is a vector? Thank you again!

Re: [deal.II] PETSc iteration does not converge
Dear Dr.Bangerth, I did nothing to verify those properties. because the single thread CG solver converged well. I used different preconditioners in parallel version and single thread version. In the parallel version I used block Jacobi and in the single thread version I used Jacobi. How can I check if the parallel blocked sparse matrix is/ isn't symmetrical and positive definite?

Re: [deal.II] PETSc iteration does not converge
Dear Dr.Bangerth, I tried both, first I tried 1e-4*system_rhs.l2_norm(), it failed. Then I tried with exact precision limits, from 1e-3 to 1e-8, all of them cannot converge. If I set the precision level as 1e-4, with or without L2 norm it stopped at step-42 with the residue 0.0113395.

[deal.II] Question about complex value finite element
Dear all, I am adding an absorbing boundary condition like step-24 did in the frequency domain, in which the time derivative gives a complex term. I also found the complex acoustic wave problem step-29 which splits the complex wave function into two real parts. What I want to know is what if I directly set up the matrix and rhs vector as complex ? Why does step-29 says "*it is often more convenient to split complex valued functions into their real and imaginary parts and use separate scalar finite element fields for discretizing each one of them*" ?

Re: [deal.II] PETSc iteration does not converge
Dear Dr. Bangerth, I tried a few levels of the tolerance, 1e-3, 1e-4 ,1e-6 and 1e-8. 1e-3 converged because that is in the same level with the solution. Error occurs below 1e-4. I have tried the Jacobi preconditioner instead of SSOR in the single thread CG version, it converged as well.

[deal.II] PETSc iteration does not converge
Dear all, I am working on acoustic wave simulation through PETSc wrapper, it gives the error message: ** Mesh Info Dimensions2 No.cells:5144 Number of active cells:5144 Number of degrees of freedom:20833 * Exception on processing: An error occurred in line <148> of file in function void dealii::PETScWrappers::SolverBase::solve(const dealii::PETScWrappers::MatrixBase&, dealii::PETScWrappers::VectorBase&, const dealii::PETScWrappers::VectorBase&, const dealii::PETScWrappers::PreconditionerBase&) The violated condition was: false Additional information: Iterative method reported convergence failure in step 65. The residual in the last step was 0.00295038. This error message can indicate that you have simply not allowed a sufficiently large number of iterations for your iterative solver to converge. This often happens when you increase the size of your problem. In such cases, the last residual will likely still be very small, and you can make the error go away by increasing the allowed number of iterations when setting up the SolverControl object that determines the maximal number of iterations you allow. The other situation where this error may occur is when your matrix is not invertible (e.g., your matrix has a null-space), or if you try to apply the wrong solver to a matrix (e.g., using CG for a matrix that is not symmetric or not positive definite). In these cases, the residual in the last iteration is likely going to be large. Aborting *** I also wrote a single thread CG version, which converges well. The preconditioner in the parallel version is blockJacobi but the single thread version I used is SSOR. Does it matter to the convergence? Thank you!

[deal.II] A small question about subdomain renumbering
Dear all, I have a question about DoFRenumbering::subdomain_wise(dof_handler). In step-17 tutorial for example, this function doesn't use the argument of n_mpi_processes, how does it know how many subdomains it should divide the dofs into? After we renumbered the subdomain and get the locally_owned_dofs_per_subomain, we can already use this_mpi_process to access the partition vector, which means the subdomain partition has been done according to the n_mpi_processes.

[deal.II] Question about the numbering of DoFs
Dear all, I am reading the page : https://www.dealii.org/current/doxygen/deal.II/classFiniteElement.html. I feel confused by the numbering of the degrees of freedom. For example: FESystem <https://www.dealii.org/current/doxygen/deal.II/classFESystem.html> fe_basis(FE_Q <https://www.dealii.org/current/doxygen/deal.II/classFE__Q.html>(2), dim, FE_Q <https://www.dealii.org/current/doxygen/deal.II/classFE__Q.html> (1),1); As mentioned in Glossary: Describing "degrees of freedom" in this context requires us to simply *enumerate* the basis functions of the space *V**h*. For *Q*1 elements this means simply enumerating the vertices of the mesh in some way, but for higher elements one also has to enumerate the shape functions that are associated with edges, faces, or cell interiors of the mesh. We have a vector u which has 2 components defined on 9 nodes. On each node, there are 2 base functions, so the degrees of freedom are 9*2*2 = 36. And we have a scalar p which has 1 component defined on 4 nodes. On each node, there is one base function, so the degrees of freedom are 4*1*1=4. The total degrees of freedom should be 36+4=40. In the webpage, it gives 2*9+4*1=22 degrees of freedom, it equals the base function with the vector components. [image: image.png] u(0) should have two base element [phi(0),0] and [phi(0) 0], u(1) should have two base elements as well [0 phi(0)] [0 phi(1)], so here should be 4 rather than 2 degrees of freedom.

[deal.II] METIS partition error
Dear all,
I am running step-17 by mpirun, it returns the error message below:
**
Exception on processing:
An error occurred in line <69> of file
in function
void dealii::SparsityTools::{anonymous}::partition_metis(const
dealii::SparsityPattern&, const std::vector&, unsigned int,

The violated condition was:
false
Additional information:
The function you called requires METIS, but you did not configure
deal.II with METIS.
This message does't appear when I use a single node to run it. Does the
sparsity tools automatically overload to partition_metis under parallel
case?
Thank you!

Dear all,
This problem has been solved. I copied the petscversion.h file to the
arch/include folder therefore cmake found all petsc files and finished
compilation.

Dear Konrad, Appreciating for your detailed explanation, it really helps!! Thank you! I am learning c++ by the means of studying deal.ii, so actually I am a layman both in deal.ii and c++.

[deal.II] Little question about constructor
Hi all, I have a question about the constructor initialization list. In some tutorials, we initialize the dof_handler in the constructor with parameter triangulation, however, the triangulation is initialized in some member function within this class, which means when we initialize the class, we have not had the triangulation yet, I don't know why this method works?

Re: [deal.II] undefined symbol: mkl_blas_dsyrk
Hi Daniel,
Thank you for your reply. I misunderstood build and install. I thought
after I setup the build folder and make install, the program should be
compiled in that build folder, because I installed the 9.0.1 version just
run the command as those in README file. Now, I first input
*cmake -DCMAKE_INSTALL_PREFIX=/**path/to/install/dir
home/yjin6/Deal.II/dealii-9.0.1 *in
*/home.yjin6/Deal.II/dealii-9.0.1/build, *
then I repeat
*cmake -DCMAKE_INSTALL_PREFIX=${HOME}**/deal.II
/home/yjin6/Deal.II/dealii-9.0.1 *
finally I make install. Is that correct?
Thanks a lot!

Re: [deal.II] undefined symbol: mkl_blas_dsyrk
Hello Daniel,
Thank you very much! I make a new folder to save the compile file for
cmake, and I used the command
*cmake -DCMAKE_INSTALL_PREFIX=${HOME}**/deal.II
home/yjin6/Deal.II/dealii-9.0.1* (substituted with my directory),
but cmake gave error warning. I substitute it with
*cmake -DCMAKE_INSTALL_PREFIX=/**path/to/install/dir
home/yjin6/Deal.II/dealii-9.0.1*
Cmake gives the message that:
-- Configuring done
-- Generating done
-- Build files have been written to: /home/yjin6/Deal.II/dealii
/home/yjin6/Deal.II/dealii is my current installation directory.
Best regards
