◆ BcePatternMesh1D
|
strong |
BCE pattern in cross section of 1-D flexible elements.
The available patterns are illustrated below (assuming 3 BCE layers):
FULL: X--X--X X--X--X X--X--X STAR: ---X--- X--X--X ---X---
◆ BcePatternMesh2D
|
strong |
BCE pattern along normal of 2-D surface of flexible elements.
The choices are illustrated below (assuming 3 BCE layers):
OUTWARD: ^ n | ...--X--X--X--... | ...--X--X--X--... ---|---------X--X--X-------- surface
CENTERED: ^ n | ...--X--X--X--... ---|---------X--X--X-------- surface | ...--X--X--X--...
INWARD: ^ n ---|---------X--X--X-------- surface | ...--X--X--X--... | ...--X--X--X--...
◆ BCType
|
strong |
◆ EosType
|
strong |
Equation of State type.
See https://pysph.readthedocs.io/en/latest/reference/equations.html#basic-wcsph-equations. An equation of state is used only with an explicit WCSPH formulation.
◆ IntegrationScheme
|
strong |
Integration scheme.
All explicit integratioon schemes use a Weakly-Compressible SPH (WCSPH) formulation in which the density is integrated and an equation of state is used to calculate the corresponding pressure. For the implicit SPH scheme, the pressure is instead updated.
