DEFINITION
SOLMTD specifies the solver type and associated control parameters used in deformation simulation.
REMARKS
The skyline solver uses the skyline storage method in conjunction with Gaussian elimination. The sparse solver is optimized for sparse matrix problems. The conjugate gradient solver is recommended when a part is well contacted due to its speed and efficient use of system memory. (For Domain decomposition) - Domain decomposition method is recommended only for single plastic object with Tet. mesh. - Domain decomposition method does not allow meshed die(s). (For Dual mesh) - Dual mesh method is recommended only for single plastic object with Tet. mesh. (For DD + DM) - DD + DM method is recommended only for single elasto-plastic object with Tet. mesh. - DD + DM method does not allow meshed die(s). Applicable simulation types: Isothermal/Non-Isothermal Deformations
