epx10 is a extension to the c++ standard library from glibc which is not in libc. To provide support for llvm compilers alonw with gcc I have changed all calls to exp10(x) to pow(10, x).
gcc versions 11 and before did not require this header to be manually specified, above that it does. As we move towrds a standardized compiler version I have brought opatIO in line with more modern gcc expectations
Aaron Dotter implimented a C++ version of Frank Timmes' fortran code helmholtz.f90. I have taken that and refactored it to work in the 4DSEE code style. This has mostly involved some light moving of stuff around. The biggest change is removing all globals, and reorienting memory to be heap allocated and contiguous. This is because there was too much memory being stack allocated.
The NewtonSolver has been subclassed to try to auto enforce the zero boundary central condition by modifying the residual vector and the gradient matrix. This is a work in progress
BREAKING CHANGE:
glVisView function now accepts a keyset to send and has an overloaded version which takes a vector and finite element space instead of just a grid function and mesh
Rescaling a mesh by a linear transformation is a useful option so that we can start with a single "base" mesh and then rescale it to the dimensions needed for our problem. This commit adds the LinearRescale option too meshIO so that a unit sphere can be turned into a sphere of arbitrary radius (as an example).
macros provides a unified place to define macros which can be accessed at other points in the code. I defined a DEPRICATION_WARNING_OFF macro so we can disable those warnings for times when we cannot control them
previously I had a lagrangian multipliers at every element; however, we are enforcing a global constraint so there need only be one lagrangian multiplier
In order to prevent traversing the YAML tree I have added a hash map (O(1) lookup) to cache already accessed config variables. I have also added a vector to store keys requested but not found so we do not need to check for those every time
At many points in the code we may want configurable options, the Config class usses a yaml file to make this easy. It also allows for namespace references "opac:lowtemp:file" etc...
