Abaqus mesh reader does not support combining element/node sets by name

1

In an Abaqus input mesh file, one can create a new nodeset by combining existing nodesets by just specifying the nodeset names. For example, if I have `NodesetA` and `NodesetB`,...

SlepcEigenSolver clear function resetting the default solver type which may prevents calling solve function properly

2

This: ``` // SLEPc default eigenproblem solver this->_eigen_solver_type = KRYLOVSCHUR; ``` in `void SlepcEigenSolver::clear ()` function is giving me a trouble. I've called `void set_eigensolver_type (const EigenSolverType est)` to set...

Add capability to construct dual meshes, relevant to saddle-point problems

6

A reference for dual mesh construction is [Busto's](https://mdpi-res.com/d_attachment/mathematics/mathematics-09-02972/article_deploy/mathematics-09-02972-v2.pdf?version=1637806891) article, titled "Staggered Semi-Implicit Hybrid Finite Volume/Finite Element Schemes for Turbulent and Non-Newtonian Flows". Cross-referenced on https://github.com/libMesh/libmesh/issues/3318#issuecomment-1154489757. This would obviously be very...
