This is a collection of several un-related fixes and improvements, to facilitate solving general unstructured Lagrange FE models read from external files. Among other things: - Tesselation of unstructured 2D...
If we have a non-rectangular domain and want to output results in a 2D raster image. (For optimal sensor placement calculations).
To allow specifying DOFs to constrain for all bases (when invoked with basis=0). This used to be the last commit in #289, which now is closed. It is not related...
After the fixup commit 8b4e1a99cc3d4c8fc33b562c4950b3943351aed8 the only regression test using periodic boundary conditions and mixed dumps core. I think the logic behind the `addPeriodicity()` calls does not account for the...
To be able to run adaptive C1-continuous plate problems (KL) with symmetry boundary conditions (the problem I showed on the whiteboard today), I need to constrain the node that is...
The first commit adds the possibility of evaluating the secondary solution at the center of each element for subsequent OSP calculations. The next two commits facilitate evaluation of nodal velocity...
Basically, adding nodal eccentricity vectors as member in class `FiniteElement`
In the early(est) days of IFEM, the SPR equation solver (from the SAM library) was the only direct solver available. Later when SuperLU was interfaced its coupling was totally neglected...
Adding two convenience methods doing some repetitive tasks, also using `std::to_string()` instead of `std::stringstream` (more compact). Then removing the three rotational DOFs if there are 6 DOFs per node (assuming...
This implements general point searching for unstructured 2D Lagrange meshes, for use in result point definition. It reuses some old Fortran codes of the 90s (the AFEM project) to conduct...
