Particle BC Shape Commands
The method to create particle-based boundary conditions was changed in NairnMPM (April 2017) and OSParticulas (revision 1170) to the method using ParticleBC and <BCShape> blocks. As a result, all boundary condition commands listed below are deprecated. They still work, but should be replaced by new methods as described below.
Line (2D or Axisymmetric)
The command to select a line through a 2D mesh in scripted files:
LoadLine (x1),(y1),(x2),(y2),<(tolerance)> (one or more load, traction, heat flux, or concentration flux condition) EndLoadLine
should be replaced with (and note changed order of parameters):
ParticleBC Line (x1),(x2),(y1)),(y2),<(tolerance)> (one or more load, traction, heat flux, or concentration flux condition) EndParticleBC
In XML files, a line is selected with:
<BCLine units='(units)' x1='(x1)' y1='(y1)' x2='(x2)' y2='(y2)' tolerance='(tolerance)'> (one or more load, traction, heat flux, or concentration flux condition) ... </BCLine>
should be replaced with
<BCShape> <Line x1='(x1)' y1='(y1)' x2='(x2)' y2='(y2)' tolerance='(tolerance)'> (one or more load, traction, heat flux, or concentration flux condition) </BCShape >
Arc (2D or Axisymmetric)
The command to select an arc through a 2D mesh in scripted files:
LoadArc (x1),(y1),(x2),(y2),(startAng),(endAng),<(tolerance)> (one or more load, traction, heat flux, or concentration flux condition) EndLoadArc
should be replaced with (and note changed order of parameters):
ParticleBC Arc (x1),(x2,(y1)),(y2),(startAng),(endAng),<(tolerance)> (one or more load, traction, heat flux, or concentration flux condition) EndParticleBC
In XML files, an line selected with:
<BCArc units='(units)' x1='(x1)' y1='(y1)' x2='(x2)' y2='(y2)' start='(startAng)' end='(endAng)' tolerance='(tolerance)'> (one or more load, traction, heat flux, or concentration flux condition) </BCLine>
should be replaced with
<BCShape> <Arc units='(units)' x1='(x1)' y1='(y1)' x2='(x2)' y2='(y2)' start='(startAng)' end='(endAng)' tolerance='(tolerance)'> (one or more load, traction, heat flux, or concentration flux condition) </BCShape >
Rectangle (2D or Axisymmetric)
The command to select rectangle in a 2D mesh in scripted files:
LoadRect (xmin),(xmax),(ymin),(ymax) (one or more load, traction, heat flux, or concentration flux condition) EndLoadRect
should be replaced with:
ParticleBC Rect (xmin),(xmax),(ymin),(ymax) (one or more load, traction, heat flux, or concentration flux condition) EndParticleBC
In XML files, a rectangle selected with:
<LdRect xmin='(xmin)' xmax='(xmax)' ymin='(ymin)' ymax='(ymax)'> (one or more load, traction, heat flux, or concentration flux condition) </LdRect>
should be replaced with
<BCShape> <Rect xmin='(xmin)' xmax='(xmax)' ymin='(ymin)' ymax='(ymax)'> (one or more load, traction, heat flux, or concentration flux condition) </BCShape>
Box or Cylinder (3D)
The command to select a 3D box or cylinder in scripted files:
LoadBox (x1),(y1),(z1),(x2),(y2),(z2),<(axis)> (one or more load, traction, heat flux, or concentration flux condition) EndLoadBox
should be replaced with (and note changed order of parameters):
ParticleBC Box (x1),(x2),(y1)),(y2),(z1)),(z2),<(tolerance)> (one or more load, traction, heat flux, or concentration flux condition) EndParticleBC
In XML files, a box selected with:
<BCBox units='(units)' xmin='(x1)' xmax='(x2)' ymin='(y1)' ymax='(y2)' zmin='(z1)' zmax='(z2)' axis='(axis)'> (one or more load, traction, heat flux, or concentration flux condition) </BCBox>
should be replaced with
<BCShape> <Box units='(units)' xmin='(x1)' xmax='(x2)' ymin='(y1)' ymax='(y2)' zmin='(z1)' zmax='(z2)' axis='(axis)'> (one or more load, traction, heat flux, or concentration flux condition) </BCBox>
