Bug Description

In general, MOOSE allows PostProcessors to have the same names as the materials or variables. However, SolutionUserObject fails to read such data from an exodus file due to the name clash. It throws in the following error which is coming from libMesh and is not directly indicative of the issue.

ERROR: incompatible variable 'var_name' has already been added for this s

A point load can be mathematically represented as a distribution, e.g., a Dirac delta. It breaks the Gridap flow, since one cannot use Gauss quadratures and numerical integration (what we usually do in FEM) to compute the integral of f*v in that case.

I don't want to consider hacks, e.g., touch the vector entry in a particular node in which you want to put the force (assuming the force is on

PSyclone supports the two command line options --profile invokes and --profile kernels. I think it would be useful if these options would be replaced with generic ones that would automatically apply any PSydata-related transformations, e.g.:

--instrument profile=kernel
--instrument read-only=invokes

etc. So the existing options for profiling would be renamed
