Re: [deal.II] dealii/spack on apple m1

Thanks for pointing this out. I think these recent fixes should be the solution to compiling on M1. I will give it a try. best praveen > On 17-Apr-2021, at 12:26 AM, Jean-Paul Pelteret wrote: > > Dear Praveen, > > Even though you’re trying to install deal.II, it would seem that the issue >

Re: [deal.II] LineMinimization and p-Laplace

Hi Julie, So as you know from the error message, the assertion on this line is being triggered. The fit function is called from this section of code

Re: [deal.II] Reading a list from parameter file

Paras, I am trying to read a list of integers from the parameter file using the dealii::Patterns::List class. However, I get a runtime error which can be reproduced using the attached MWE. I also tried the approach described (for tensor) in

Re: [deal.II] interpolate FE_Nelelec

To add to Wolfgang’s comment, you can have a look at the compute_edge_projection_l2() function that forms a part of the function that computes

Re: [deal.II] interpolate FE_Nelelec

Dear Jean-Paul, Thank you for your reply. I am solving a very standard curl(1/mu(curl(A)) = J problem as described in the paper of Oszkar Biro. https://ieeexplore.ieee.org/document/497322 No gauge. I need interpolation to project the vector current potential on the shape functions. I just

[deal.II] Re: interpolate FE_Nelelec

Ah! Now I got it. The function you suggested indeed vector-valued. It works just fine now. Thanks a lot! I was trying to output the function values via “vector_value” method like this: class CustomFunction : public Function<3> { public: virtual void vector_value( const Point<3> & p,

Dear Praveen, Even though you’re trying to install deal.II, it would seem that the issue that you documented sysctl: unknown oid 'machdep.cpu.leaf7_features' sysctl: unknown oid 'machdep.cpu.vendor' sysctl: unknown oid 'machdep.cpu.model' sysctl: unknown oid 'machdep.cpu.leaf7_features' sysctl:

Re: [deal.II] interpolate FE_Nelelec

Dear John, I’m not sure that there is an interpolation function that would work in that way for Nedelec elements (there is VectorTools::project_boundary_values_curl_conforming_l2() for

Re: [deal.II] Re: interpolate FE_Nelelec

Dear Simon, Thank you for your reply. Your suggestion definitely works. I used functions that output one component when I was interpolating scalar potentials. It works well. However, the FE_Nedelec is different. It implements edge elements. They are vector-based. That is, functions are

[deal.II] Re: interpolate FE_Nelelec

Hi, I don't have any experience with FE_Nedelec, but the error message states that the function you are trying to interpolate has 1 component, while the element has dim components. If you implemented your own Function, you need to make sure it has dim-components by calling the constructor of

[deal.II] interpolate FE_Nelelec

Hello, It seems I am unable to find a function similar to VectorTools::interpolate for FE_Nedelec finite elements. The existing implementation of this functions gives the following run-time error: *An error occurred in line <556> of file in function* * void
