Basic functions

Fiber patches

openseestools.patchRect2d(matTag, nf, width, startHeight, endHeight)

Create a quadrilateral patch suitable for two-dimensional analyses.

All fibers are placed on the z-axis.

Parameters:

• matTag (int) – Tag of the uniaxial material to use.

• nf (int) – Number of fibers in the patch.

• width (float) – Width of the patch.

• startHeight (float) – Starting height of the patch.

• endHeight (float) – Ending height of the patch.

openseestools.patchHalfCircTube2d(matTag, nf, center, side, D, t)

Create a set of fibers to describe half a circular tube.

Fibers are suitable for two-dimensional analyses since all fibers are placed on the Z-axis.

Parameters:

• matTag (int) – Tag of the uniaxial material to use.

• nf (int) – Number of fibers along the height of the section.

• center (float) – Y-axis location of the center of the tube.

• side ({'top', 'bottom'}) – Side of the tube to create.

• D (float) – Diameter of the tube.

• t (float) – Thickness of the tube.

Raises:

ValueError – if side is not ‘top’ or ‘bottom’ if D is not a positive value if t is not a positive value if t is more than 0.5*`D`
