\n
test_FEMBEM usage:
\n
-----------------
\n\n
"
" -nbpts: Number of unknowns of the global linear system. Default: 16000 (can be in floating point notation, like 1.2e4).
\n
"
" -nbrhs: Number of right-hand sides of the global linear system. Default: 1.
\n
"
" -lambda: Wavelength (for oscillatory kernels). Mutually exclusive with -ptsperlambda. Default lambda is set with 10 points per wavelength.
\n
"
" -ptsperlambda: Points per wavelength on the main cylinder (for oscillatory kernels). Default: 10.
\n
"
"
\n
"
" BEM tests use a surfacic cylinder with an optionnal cylinder detail, defined with:
\n
"
" -radius: Radius of the cylinder. Default is 2.
\n
"
" -height: Height of the cylinder. Default is 4.
\n
"
" -height: Height of the cylinder detail. Default is 0.5.
\n
"
"
\n
"
" FEM and FEM/BEM tests use a volumic cylinder, defined with:
\n
"
" -radius: Radius of the cylinder. Default is 2.
\n
"
" -height: Height of the cylinder. Default is 4.
\n
"
" For FEM/BEM, the BEM is done on the outer surface of the cylinder (without the upper and lower disks).
\n
"
"
\n
"
" Options for HMAT tests
\n
"
" --use_hmat_shuffle: Using Hmat shuffle clustering. Default: NO.
\n
"
" --hodlr: Using HODLR. Default: NO.
\n
"
" --hmat-eps-assemb: Compression epsilon. Default: 1e-4.
\n
"
" --hmat-eps-recompr: Recompression epsilon. Default: 1e-4.
\n
"
" --hmat-leaf-size: Maximum leaf size. Default: -1 (set by hmat itself).
\n
"
" Compression algorithm: default is ACA+, it can be changed with:
\n
"
" --hmat-svd: Using SVD compression.
\n
"
" --hmat-aca-partial: Using ACA with partial pivoting.
\n
"
" --hmat-aca-full: Using ACA with full pivoting.
\n
"
" Solver: default is LDLt, it can be changed with:
\n
"
" --hmat-lu: Force LU decomposition.
\n
"
" --hmat-llt: Force LLt decomposition (for symmetric matrices).
\n
"
" --hmat-ldlt: Force LDLt decomposition (for symmetric matrices).
\n
"
" --hmat-coarsening: Coarsening of the HMatrix.
\n
"
" --hmat-recompress: Recompress the HMatrix.
\n
"
" --hmat-val-null: Validate the detection of null rows and columns.
\n
"
" --hmat-val: Validate the rk-matrices after compression.
\n
"
" --hmat-val-threshold: Error threshold for the compression validation.
\n
"
" --hmat-dump-trace: Dump trace at the end of the algorithms (depends on the runtime).
\n
"
" --hmat-val-rerun: For blocks above error threshold, re-run the compression algorithm.
\n
"
" --hmat-val-dump: For blocks above error threshold, dump the faulty block to disk.
\n
"
" Runtime: default (and only choice with hmat-oss) is sequential.
\n
"
" --hmat-seq: Use the sequential runtime.
\n
"
"
\n
"
" -h/--help: Display this help
